A Survey Of Stainless Steel In Medical And Surgical Application, Noah Slack, Clint Balch

ME 4133/6133 Mechanical Metallurgy

Stainless steels can be separated into four families based on the microstructure of the material: Austenitic, Ferritic, Martensitic, and Duplex. Each family provides a specific set of advantages and disadvantages, and material selection should be based on the specific application the material will be used for. For this study, the processing, microstructure, and performance of the four families of stainless steels will be compared in the context of medical device applications. The most important factors in medical device materials are biocompatibility, surface properties, mechanical properties and life span/corrosion resistance. This study will focus on medical devices that will be permanently …

The Process-Structure-Property-Performance Of Aisi 1020​, Jonathan Wellman, Tate James, Robbie Christman, Brian Broom

ME 4133/6133 Mechanical Metallurgy

AISI 1020 is widely used in many different industries due to its high strength, high ductility, high machinability, and good weldability. AISI 1020 has a number of applications. Low carbon steel can be used on a macroscale to build bridges, and low carbon steel can be used on smaller scales such as Lawnmower blades. Low carbon steel is the material of choice for lawn mower blades because of its ability to bend before it breaks. The ductile attribute of low carbon steel also has many other benefits.

Research into the structure and properties of duplex stainless steel and the processes it undergoes will indicate how duplex …

Ar400 Wear Plates, Jase Tatum, Bryson Miller, John Howell, Aaron Alexander

ME 4133/6133 Mechanical Metallurgy

Wear resistance is an invaluable performance metric for most metallic components found in mechanical systems. Our research focused on AR400, a steel alloy known for its wear resistance capabilities, in an effort to determine what factors might be attributed to its performance in wear applications. After establishing the processing techniques and resulting material structures that give AR400 such an edge in extreme wear conditions, our goal is to determine indicators of wear resistance that can be used to distinguish excellent wear resistant alloys from average or subpar performers against wear.

3xx Aluminum Alloys For Ice Implementation, Kyle A. Taylor, Eric Cleckner, Jeffery Garrett

ME 4133/6133 Mechanical Metallurgy

The material to be explored for the purpose of this project relates to the Aluminum alloys used in the majority of modern engine “heads” and a number of engine “blocks”. The Aluminum used for these engine applications vary slightly across different manufacturers in their processing, structure and ultimate properties, despite their nearly identical performance applications. Part of the interest in this particular subject is the slight variations across manufacturing that result in different performance. Regardless of idiosyncrasies, these Al alloys are expected to perform under varying temperatures, with the ability to elastically deform and return to their original shape. They …

Terror Tactics: Vehicular Attacks In Israel, Garrett Smith

Honors Theses

Vehicular ramming attacks are a relatively new phenomenon within transnational terrorism. Their use is concentrated heavily within Israel and the West Bank. Using data from the University of Maryland’s Global Terrorism Database, I conduct an analysis of automobilebased terrorist attacks in Israel and the West Bank. I identify examine the relationship between Israeli counterterrorism policy, specifically the institution of barriers to physical movement, and the adoption of vehicle ramming tactics. These walls and checkpoints inadvertently provoke vehicle ramming attacks, even if effective at reducing firearm and explosive-based attacks. Exploration of existing literature on terrorist tactic selection suggests that vehicular attacks …

Additive Manufacturing Of Cork, A Cold Spray Technology, Kimberly Kay Dickey

Theses and Dissertations

Cold Spray Additive Manufacturing is a technology capable of mass manufacturing components with complicated geometry and coating substrates in hard-to-reach areas. In addition, cold spray also has the ability of conducting a green manufacturing process, with zero waste of renewable feed material, and zero gas and chemical emission. This paper investigates solely cold spray as an additive manufacturing technology with cork as the natural material. CFD results were used to predict the physical behavior of air and the cork particles. After unsuccessful coatings, final results showed that when moisture is added, cork is successfully cold sprayed, and agglomeration is experienced. …
