The correlation between wall thickness and properties of HPDC Magnesium alloys

A systematic study was carried out to evaluate the correlation between high pressure die casting (HPDC) parameters and the mechanical properties of Magnesium alloys. The tested alloys included two conventional alloys: AZ91D and AM50A and a newly developed alloy, MRI153M.The nature of the above correlations was semi-empiric, based on computer simulation of the die casting process using MAGMA® simulation software and actual measurements of mechanical properties. This was combined with microstructure analysis with the aim of understanding the interaction between high pressure die casting and the obtained properties. Special attention was also given to the complex effect of the wall thickness of die cast specimens and their subsequent porosity level.
