Evaluation Of Metallurgical And Mechanical Properties Of Alsi10mg Produced By Selective Laser Melting, Luke J. Suttey
Evaluation Of Metallurgical And Mechanical Properties Of Alsi10mg Produced By Selective Laser Melting, Luke J. Suttey
Graduate Theses & Non-Theses
Selective laser melting (SLM) additive manufacturing (AM) of metal powders has long been a focus in the study of AM due to the possibility of weight reduction, complex shape formation, and production cost savings. Although applicable to a variety of metals SLM AM of the AlSi10Mg alloy was studied in an attempt to characterize the effect of processing parameter and build angle variation on the final microstructural, fractographic, and mechanical properties of parts produced without any thermal post-processing techniques. Research was conducted on five build angles (0°, 30°, 45°, 60°, and 90°), and three Global Energy Densities (GED) (37.15, 45.39, …
An Environmental And Hydrogeological Investigation In The South Hebgen Basin, Montana, Joe Schmechel
An Environmental And Hydrogeological Investigation In The South Hebgen Basin, Montana, Joe Schmechel
Graduate Theses & Non-Theses
This study was conducted to develop a hydrogeologic framework, and address water quality concerns in the South Hebgen Basin, near the town of West Yellowstone, Montana. The main goals of this research were to: (1) Develop a conceptual model of groundwater flow within the confined aquifer. (2) Use naturally occurring chemical tracers to investigate the confined aquifer’s extent and the connectivity. (3) Identify the influence of geothermal features on water chemistry. (4) Identify water quality issues related to arsenic (As) and fluoride (F-). Long-term static water elevation plots and surface water flow, combined with water ion chemistry were …
Thermal Processing And Mechanical Properties Of Beta Phase Titanium Alloys For Biomedical Applications, Ethan Wood
Thermal Processing And Mechanical Properties Of Beta Phase Titanium Alloys For Biomedical Applications, Ethan Wood
Graduate Theses & Non-Theses
The past few decades have seen an increase in the use of beta titanium alloys as structural biomaterials. Their combination of excellent mechanical properties, corrosion resistance and biocompatibility, along with a lower Young’s modulus than stainless steel, cobalt-chromium and commercially pure titanium make the beta titanium alloys ideal biomaterials. This work evaluates the use of three beta titanium alloys for biomedical applications. Three beta titanium alloys, Ti 15-3-3-3, Ti SP-700 and Ti Beta-C, underwent thermal processing to optimize mechanical properties. The alloys were subjected to tensile testing, hardness testing, fatigue testing, optical microscopy and SEM fracture analysis in order to …
Microradiography Of Metals And Alloys Using A Medical X-Ray Unit, W. R. Byrne
Microradiography Of Metals And Alloys Using A Medical X-Ray Unit, W. R. Byrne
Bachelors Theses and Reports, 1928 - 1970
There is no doubt that the microradiograph technique is of value to the metallurgist. A three-dimensional picture to supplement the photomicrographs should give a true picture of the microstructure. Microradiography can be used where etchants can not differentiate between the various components or where no etchant can be found suitable for a particular alloy.
Faunal Studies Of The Sappington Sandstone Of Southwestern Montana, Howard E. Banta
Faunal Studies Of The Sappington Sandstone Of Southwestern Montana, Howard E. Banta
Bachelors Theses and Reports, 1928 - 1970
The exact upper boundary of the Devonian of Montana has long been a controversy, as is true of the Devonian-Mississippian contact in many other localities. In an effort to delimit the upper Devonian, various paleontologic studies have been made, more especially in the southwestern part of the state.
Fauna Of The Pilgrim Formation Of The South Boulder Creek Area In Southwestern Montana, John T. Eastlick
Fauna Of The Pilgrim Formation Of The South Boulder Creek Area In Southwestern Montana, John T. Eastlick
Bachelors Theses and Reports, 1928 - 1970
This paper, a study of the fauna of the Pilgrim formation at South Boulder Creek in southwestern Montana, represents a laboratory study of the fossil specimens collected by Dr. Alvin Hanson during the summer of 1949. The scope of investigation includes identification and classification of the faunas, their stratigraphic relationship and zonal subdivisions.
An Investigation Of The Gallium-Indium Binary System, Allen D. Kennedy
An Investigation Of The Gallium-Indium Binary System, Allen D. Kennedy
Bachelors Theses and Reports, 1928 - 1970
Twenty-four alloys, at 5 weight per cent or smaller intervals, were investigated by the thermal method. Very low temperatures had to be attained, because most of the alloy melts supercooled remarkably. Analysis showed only a liquidus and solidus line, and the solidus temperature was the same for each alloy.

The Alloys Of Gallium And Indium, C. J. Adams
Bachelors Theses and Reports, 1928 - 1970
Thermal analysis VIPS used to construct cooling and heating curves from which the phase diagram was determined. The data for the entire set of cooling curves were obtained by the use of mercury thermometers.

Upper Mississippian Faunas Of Western Montana, James King
Upper Mississippian Faunas Of Western Montana, James King
Bachelors Theses and Reports, 1928 - 1970
The author has made a study of an assemblage of fossils from the Blacktail Range near Dillon Montana with the purpose in view of attempting a correlation of that group with the fauna of the Big Snowy Group. Fossils have also been obtained from a limestone formation in northwestern Montana and from four different areas in the Amsden formation in central and western Montana.
An Investigation Into The Recovery Of Indium From Fume Residue, Emery J. Turner
An Investigation Into The Recovery Of Indium From Fume Residue, Emery J. Turner
Bachelors Theses and Reports, 1928 - 1970
Several months were required to produce a single gram of indium. Consequently, the industrial history of the metal is extremely short. In view of the unique properties that indium has demonstrated in this short period, it is probable that indium is still in its early stage of development. However, the commercial applications of the metal are well established and indium is now produced on a commercial scale. It is obtainable as the metal or in solution for electroplating.
Measurements Of The Magnetic Permeabilities Of The Iron-Manganese Alloy System Prepared By The Methods Of Powder Metallurgy, O. Cihad Onbulak
Measurements Of The Magnetic Permeabilities Of The Iron-Manganese Alloy System Prepared By The Methods Of Powder Metallurgy, O. Cihad Onbulak
Bachelors Theses and Reports, 1928 - 1970
Powder metallurgy is a branch of metallurgy which produces metallic compacts in their final forms by means of pressure and heat-treatment from the powders. The products of powder metallurgy are being used in our daily lives quite often. For example, the tungsten wires in the electric bulbs to the silver-tin fillings of our teeth.
