Extremely Low Cycle Fatigue Behavior Of Additively Manufactured 17-4ph Stainless Steel, Kaley Collins May 2020

Extremely Low Cycle Fatigue Behavior Of Additively Manufactured 17-4ph Stainless Steel, Kaley Collins

Civil Engineering Undergraduate Honors Theses

Steel structures survive seismic loading thanks to components capable of dissipating large amounts of energy through large deformations. Future optimizations of these components include complex free-form geometries that are difficult to fabricate with traditional casting processes. Additive manufacturing (AM) is an alternative for producing optimized free-form geometries. AM material contains significant differences in microstructural characteristics and mechanical behavior compared to its wrought counterparts. Research has been conducted to understand the effect of microscopic features in the high cycle fatigue (HCF) and low cycle fatigue (LCF) regimes. This study focuses on the behavior of 17-4 Precipitation Hardening (PH) stainless steel in ...

Galvanic Corrosion In Aluminum/Steel Joints, Maegan Saul Jan 2020

Galvanic Corrosion In Aluminum/Steel Joints, Maegan Saul

Williams Honors College, Honors Research Projects

As car manufacturers seek to use lighter weight materials, aluminum is being more commonly used in the construction of vehicles. However, the strength of steel cannot be matched and both metals are necessary, leading to the joining of dissimilar metals. This connection of different metals leads to a galvanic coupling and subsequent corrosion of the less noble metal. This project aims to observe the corrosion and galvanic coupling behavior of aluminum alloys and carbon steel so that a model may be produced which can accurately predict the expected responses of the metals in various environments. Better, more accurate modeling of ...

Identification Of Bridges With Fracture-Prone Details, Theodore Hopwood Ii, Rick Younce, Sudhir Palle Oct 2019

Identification Of Bridges With Fracture-Prone Details, Theodore Hopwood Ii, Rick Younce, Sudhir Palle

Kentucky Transportation Center Research Report

Welded steel girder bridges can contain details that can high welding and service stresses and are termed constraintinduced fractures (CIF). The Kentucky Transportation Cabinet has steel bridges with weld details known to cause CIFs whose girders have experienced fracture events. The Cabinet’s bridge inventory was reviewed and additional candidate bridges with potential CIF details were identified. A review of bridge plans and pictures along with followup field investigations pinpointed bridges with CIF details that warrant up-close (i.e., arm’s length) inspections. Several uninspected bridges were identified as candidates for inspection to determine if they contain CIF details. Guidance ...


Experimental Calibration Of Centrally Loaded Built-Up Battened Compression Members, Ghada El-Mahdy Ph.D., P.Eng. Sep 2019

Experimental Calibration Of Centrally Loaded Built-Up Battened Compression Members, Ghada El-Mahdy Ph.D., P.Eng.

Civil Engineering

There is a large diversity in the requirements for designing built-up compression members between international design codes. Most codes, including the North American standards and specifications specify the use of an equivalent or modified slenderness ratio. In general, all North American standards and specifications agree on the need of using a modified slenderness ratio, but differ in the factor used to multiply the local slenderness ratio. Theoretically it is difficult to estimate the exact value of this factor, and using experimental methods does not capture the exact value of this factor either. Hence, a different approach is needed to determine ...

Direct Patterning Of Nature-Inspired Surfaces For Biointerfacial Applications, Feyza Dundar Mar 2019

Direct Patterning Of Nature-Inspired Surfaces For Biointerfacial Applications, Feyza Dundar

Doctoral Dissertations

There are three major challenges for the design of patterned surfaces for biointerfacial applications: (i) durability of antibacterial/antifouling mechanisms, (ii) mechanical durability, and (iii) lifetime of the master mold for mass production of patterned surfaces. In this dissertation, we describe our contribution for the development of each of these challenges.

The bioinspired surface, Sharklet AFTM, has been shown to reduce bacterial attachment via a biocide-free structure-property relationship effectively. Unfortunately, the effectiveness of polymer-based sharkskin surfaces is challenged over the long term by both eventual bacteria accumulation and a lack of mechanical durability. To address these common modes of ...

Effects Of Steel Type And Sandblasting Pretreatment On The Solid-Liquid Compound Casting Characteristics Of Zinc-Coated Steel/Aluminum Bimetals, Jesik Shin, Taehyeong Kim, Kyoungmook Lim, Hoon Cho, Daeho Yang, Changyeol Jeong, Sung Yi

Mechanical and Materials Engineering Faculty Publications and Presentations

Effects of zinc-coated steel type and steel surface sandblasting pretreatment in the solid-liquid compound casting of layered type steel/aluminum bimetals were investigated. The Zn coating behavior and its effects on interfacial microstructure evolution and fracture mechanism were also discussed. The aluminum fluidity in thin plate type flow channels formed by the steel insert and the mold wall primarily depended on the insert surface roughness and secondarily on the wettability. As-galvanized (GI) steel/aluminum bimetal joints showed the bonding strength of 20 MPa and more, while galvannealed (GA) steels showed poor bonding. The interfacial bonding zone consisted of most Al13Fe4 ...


Metric Coil Car, Abigail Eberly Jan 2019

Metric Coil Car, Abigail Eberly

Williams Honors College, Honors Research Projects

Coil cars are a vital part of many steel mills. They allow mills to easily transfer a coil from one location to another without the use of a crane, manual labor, or other extraneous forces. Steel Equipment Specialists, or SES, gets multiple orders every year for coil cars. While the general functions and goals of the cars remains consistent, the details, such as the size of the car, the distance between rails, and the weight/ size of the coils differs between each place. Due to this variety, SES has requested a coil car that can easily be manipulated and produced ...

Faculty of Engineering and Information Sciences - Papers: Part B

This paper presents analytical modelling of the axial-flexural behaviour of Reactive Powder Concrete (RPC) columns reinforced with and without steel fibres of different types (industrial and waste) in individual and hybrid forms. An analytical stress-strain model for unconfined RPC was used for the analysis of the axial loads and bending moments of the fibrous RPC columns. The layer-by-layer numerical integration method was used to calculate the axial load and bending moments in this study. The analytically developed axial load-bending moment ( P-M ) interaction diagrams were validated by using experimental results from the literature. A para- metric study was carried out to ...


Effect Of Continuity Plate Eccentricity On The Performance Of Welded Beam-To-Column Connections, Jason Thomas Norwood Dec 2018

Effect Of Continuity Plate Eccentricity On The Performance Of Welded Beam-To-Column Connections, Jason Thomas Norwood

Theses and Dissertations

Beam-to-column connections in structural steel buildings may have varying degrees of rotational restraint and varying degrees of moment transfer. In fully restrained moment connections, shear is typically transferred through the beam web, while the moment is mostly transferred through the beam flanges which create tension/compression force couples. Column sections that are incapable of resisting these flange forces are often retrofitted with continuity plates within the connection region to improve capacity. In cases of unequal beam depths on either side of the column, an eccentricity between the framed-in beam flange and continuity plate may be required; however, limited research exists ...


Optimization Of The Practice Of Slow Cooling Steel Bars: A Redesign And Modernization Of Materials, Eryn Johnston Dec 2018

Optimization Of The Practice Of Slow Cooling Steel Bars: A Redesign And Modernization Of Materials, Eryn Johnston

Mechanical Engineering Undergraduate Honors Theses

Throughout the process of steel making, certain grades of steel are a higher risk for defects caused by the inability to quickly diffuse hydrogen through the steel when cooled to room temperature at a normal rate based on the ambient air temperature. To reduce the hydrogen flaking defects that are caused due to hydrogen entrapment in the steel, the process of slow cooling is utilized. This process reduces the cooling rate of steel bars by keeping them at a higher temperature for extended periods and in turn gives the hydrogen a chance to fully dissipate from the steel. In many ...


Temper Response Of A Vanadium Microalloy Steel, Bradley W. Hostetler Jun 2018

Temper Response Of A Vanadium Microalloy Steel, Bradley W. Hostetler

Materials Engineering

This investigation details the effect of a quench-and-temper processing treatment on the mechanical properties of a microalloy steel being considered for use as a pipeline flange. Microalloy steels are normally processed via Thermo-Mechanically Controlled Processing (TMCP) due to the increased strength from ferrite grain refinement; however, the geometry of a pipeline flange requires post processing beyond TMCP which diminishes the strengthening effect provided by TMCP. The purpose of this research project is to determine the mechanical properties produced when a vanadium microalloy steel is quenched and tempered. The two major considerations are the effect of tempering time on properties and ...


Fatigue Investigation Of Slit Rib-To-Floor Beam Connections In Steel Orthotropic Bridge Decks, Jayne Marks May 2018

Fatigue Investigation Of Slit Rib-To-Floor Beam Connections In Steel Orthotropic Bridge Decks, Jayne Marks

Theses and Dissertations

The steel orthotropic bridge deck (SOBD) is a bridge deck system which consists of longitudinal open or closed ribs that pass through transverse floor beams with a continuous steel deck plate on top. All of these components are joined using welded connections which can be costly to fabricate and prone to fatigue cracks. The rib-to-floor beam (RFB) connection in an SOBD is labor intensive and fatigue sensitive. In the past, the RFB connection has either been a fully fitted connection or a connection with an extended cut-out which is larger than the opening in the floor beam web for the ...

Efficiency Of Solid Inclusion Removal From The Steel Melt By Ceramic Foam Filter: Design And Experimental Validation, Soumava Chakraborty, Ronald J. O'Malley, Laura Bartlett, Mingzhi Xu

Materials Science and Engineering Faculty Research & Creative Works

An investigation was performed to measure the efficiency of solid alumina inclusion removal by filtration during casting. A mold design was developed using modeling software to produce two castings that fill simultaneously, one with a filter and the other without a filter. The design avoided vortex formation and thus air entrainment, which helped to avoid reoxidation inside the mold cavity. Samples from these castings were analyzed utilizing an SEM/EDS system with automated feature analysis (AFA) to measure the efficiency of inclusion removal using a 20 ppi zirconia foam filter. This study also documents the occurrence of inclusion flotation and ...

Applications Of Open Source Gmaw-Based Metal 3-D Printing, Yuenyong Nilsiam, Paul G. Sanders, Joshua M. Pearce

Department of Materials Science and Engineering Publications

The metal 3-D printing market is currently dominated by high-end applications, which make it inaccessible for small and medium enterprises, fab labs, and individual makers who are interested in the ability to prototype and additively manufacture final products in metal. Recent progress led to low-cost open-source metal 3-D printers using a gas metal arc welding (GMAW)-based print head. This reduced the cost of metal 3-D printers into the range of desktop prosumer polymer 3-D printers. Consequent research established good material properties of metal 3-D printed parts with readily-available weld filler wire, reusable substrates, thermal and stress properties, toolpath planning ...

Effects Of Microstructure And Crystallography On Mechanical Properties Of Cold-Rolled Sae1078 Pearlitic Steel, Y. Liu, C. D. Yang, M. Liu, C. H. Wang, Y. C. Dai, X. Li, Alan M. Russell, C. X. Zhang, Z. H. Zhang, G. H. Cao

Materials Science and Engineering Publications

The evolution of the microstructure and crystallography in SAE1078 pearlitic steel sheets under different cold-rolling reductions of up to 90% were quantified using transmission electron microscopy (TEM), electron backscatter diffraction (EBSD), and X-ray diffraction (XRD). The mechanical properties were determined by tensile testing at room temperature. TEM analysis showed that the pearlite structure was obviously refined with the interlamellar spacing decreasing to about 57 nm at the rolling reduction of 90%. EBSD investigations indicated that the ferrite exhibited a {001}texture in the 90% cold-rolled pearlitic steel. The dislocations were mainly concentrated during cold rolling between the 10% and 70 ...

Performance Evaluation And Lubrication Mechanism Of Water-Based Nanolubricants Containing Nano-Tio2 In Hot Steel Rolling, Hui Wu, Jingwei Zhao, Liang Luo, Shuiquan Huang, Lianzhou Wang, Suoquan Zhang, Sihai Jiao, Han Huang, Zhengyi Jiang

Faculty of Engineering and Information Sciences - Papers: Part B

Hot rolling tests of a low-alloy steel were conducted at a rolling temperature of 850 °C under different lubrication conditions, including benchmarks (dry condition and water) and water-based nanolubricants containing different concentrations of nano-TiO2 from 1.0 to 8.0 wt%. The effects of nanolubricants on rolling force, surface roughness, thickness of oxide scale, and microstructure were systematically investigated through varying nano-TiO2 concentrations. The results show that the application of nanolubricants can decrease the rolling force, surface roughness and oxide scale thickness of rolled steels, and refine ferrite grains. In particular, the nanolubricant containing an optimal concentration (4 ...

Comparison Of Gmaw And Saw For Ngw Of 50 Mm Q&T Steel Plate, Druce Patrick Dunne, Willy Pang

Faculty of Engineering and Information Sciences - Papers: Part B

A one-pass-per-layer technique was used for narrow gap welding (NGW) of 50 mm thick plate of quenched and tempered steel with 690 MPa minimum yield strength. GMAW and SAW were investigated for pulsed and non-pulsed welding using the same 1.2 mm strength-matching welding consumable and the same nominal heat inputs for each of the pulsed and non-pulsed welds. The welds were defect-free and the hardness, tensile strength and Charpy impact energies were generally consistent with high weldment integrity. Pulsing of the welding current had the effect of slightly increasing side-wall fusion, flattening the weld bead and decreasing its volume ...


Microstructural Evaluation Of Hydrogen Embrittlement And Successive Recovery In Advanced High Strength Steel, Quentin Scott Allen Dec 2017

Microstructural Evaluation Of Hydrogen Embrittlement And Successive Recovery In Advanced High Strength Steel, Quentin Scott Allen

Theses and Dissertations

Advanced high strength steels (AHSS) have high susceptibility to hydrogen embrittlement, and are often exposed to hydrogen environments in processing. In order to study the embrittlement and recovery of steel, tensile tests were conducted on two different types of AHSS over time after hydrogen charging. Concentration measurements and hydrogen microprinting were carried out at the same time steps to visualize the hydrogen behavior during recovery. The diffusible hydrogen concentration was found to decay exponentially, and equations were found for the two types of steel. Hydrogen concentration decay rates were calculated to be -0.355 /hr in TBF steel, and -0 ...

This project conducted a multi-hazard study on steel buildings considering both seismic and fire damage. A literature review of the behavior of steel-framed buildings due to fires after earthquakes, known as post-earthquake fires (PEF), is offered. The new PEF methodology, delivered in this study, starts with creating a three dimensional (3D) model of the examined steel building using the finite element method software, ABAQUS. Next, varying intensities of seismic and fire hazards ...


Condition Factor Calibration For Load And Resistance Factor Rating Of Steel Girder Bridges, Joshua Steelman, Pranav M. Shakya Jun 2017

Condition Factor Calibration For Load And Resistance Factor Rating Of Steel Girder Bridges, Joshua Steelman, Pranav M. Shakya

Nebraska Department of Transportation Research Reports

Load and Resistance Factor Rating (LRFR) is a reliability-based rating procedure complementary to Load and Resistance Factor Design (LRFD). The intent of LRFR is to provide consistent reliability for all bridges regardless of in-situ condition. The primary difference between design and rating is the uncertain severity and location of deterioration, including the potential future loss of strength for an element already evidencing deterioration. Ostensibly, these uncertainties are addressed by applying an additional strength reduction factor: the condition factor, ϕc. Currently, condition factors are nominally correlated to the condition of the member, which can be Good, Fair, or Poor. However, definitions ...


Process Development And Implementation For The Imaging Of Heat Treated A2 Steel For Consolidation Into An Atlas, Jessica Roberts May 2017

Process Development And Implementation For The Imaging Of Heat Treated A2 Steel For Consolidation Into An Atlas, Jessica Roberts

Senior Honors Projects, 2010-2019

Material processes, properties, and microstructure are interconnected, often visualized as the points of a triangle. Changing the process a material goes through will in turn change the properties and microstructure of that material. In materials research and education (specifically with metals), comparison between research or experiment results and scholarly-accepted results is important. When reading textbooks addressing different properties of metals and the process of metal treatment, images are often shown of the various microstructures associated with each property or process stage. The difficulty comes in trying to compare the stages or properties to one another; often different materials and processes ...
