Fluidity of Mg–Al–Ca alloys in the high-pressure die casting process
-
Peng Zhao
Abstract
The fluidity of Mg – Al – Ca alloys under high-pressure die casting conditions was studied using fluidity tests with spiral specimens. The flow behavior analyses suggest that flow with zero superheat plays a more important role under high-pressure die casting conditions than gravity casting. This can be attributed to the difference between the two kinds of casting process. Fluidity results with a degree of superheat were interpreted on the basis of the effects of calcium on (1) latent heat, (2) viscosity and (3) solidification characteristics. The latent heat and phase accumulation formed by high pressure are the important factors influencing the fluidity of magnesium alloys in the high-pressure die casting process.
