Process-Structure-Property Relationships For High Pressure Die-Cast Magnesium Alloys, Pouya Sharifi

Electronic Thesis and Dissertation Repository

The primary goal of this study was to conduct experiments and simulation modeling to determine the relevant filling and solidification process parameters that influence microstructural features of the high-pressure die-cast magnesium alloy AM60. This work continues from the previous research that has been carried out by Dr. Jeff Wood’s research group over the last sixteen years.

Metallographic and spherical microindentation were used to analyze the influence of microstructural features on the flow stress for both skin (finer grain sizes) and core (larger grain sizes) of high pressure die castings (HPDC), as well as different regions of gravity cast stepped-plate. It …
