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 …

Tungsten: The Strongest Natural Metal On Earth, Haley E. Holland, Razan Khadka, Lee Marble, Kaleb Tutor

ME 4133/6133 Mechanical Metallurgy

The overall objective of this project was to construct a process-structure-property-performance (PSPP) map for a chosen metallic material. The material chosen by the group is tungsten (W). Tungsten is a rare, naturally occurring element and is usually found in the form of ores. It is known predominantly for its ability to withstand extreme temperatures, as well as its high tensile strength. The PSPP map displays many specifications of tungsten in each of the four categories and further details regarding each specific linkage, or subcategory, within the map are written throughout the research paper.

Along with the four specific categories outlined …
