Shear Rolling of Magnesium Sheet |
The use of cast Mg components in automotive applications is limited by many technological and economic hurdles. Magnesium die castings have found application in certain structural components however the actual ductility of these components can be very low. Most of these defects and microstructure features that decrease the ductility in high pressure die casting. Magnesium castings are a result of the mold filling process and high cooling rates due to the contact between the molten alloy and metal die/shot-sleeve. In order to reduce casting defects and improve the microstructure, models must be developed for the prediction of defects, databases for microstructural evolution must be created, and mechanical properties in the mushy zone of Mg alloys must be measured. This thrust will enable the production of Mg components with improved quality, increase the casting yield, and decrease casting cost.
