Intrinsic Mechanical Properties Of Zirconium Carbide Ceramics, Nicole Mary Korklan
Masters Theses
“This research focuses on the processing and mechanical properties of zirconium carbide ceramics (ZrCx). The first goal of this project was to densify near stoichiometric (i.e., x as close to 1 as possible) and nominally phase pure ZrCx. The maximum stoichiometry achieved for the ZrCx (C/Zr ratio of 0.92) was measured using gas fusion analysis. Hot pressing was used to obtain dense ZrCx. Archimedes was used to determine the relative density of hot pressed ZrCx at > 95%. Scanning electron microscopy (SEM) was used to determine the overall microstructure of the hot pressed …

Performance Evaluation Of Alsi10mg Fabricated By A Selective Laser Melting Process, David Michael Murphy
Masters Theses
“Selective laser melting is becoming a widely used additive manufacturing technique that melts metal powder in a layer by layer process in order to build a desired part or geometry. Like many additive processes, selective laser melting allows for fabrication of parts with complex geometries. In order to fabricate a fully dense part there are a number of variables to take into account including: powder characteristics, laser parameters, and environmental parameters. Each of these variables can affect the microstructure and thus the mechanical performance of an additively manufactured part. In this work, the aluminum alloy AlSi10Mg was investigated. AlSi10Mg is …
