Design Guidelines for Components Die Cast in Creep-Resistant Magnesium Alloys MRI153M and MRI230D 2007-01-1034

Magnesium high pressure die casting alloys MRI 153M and MRI 230D offer attractive properties at elevated temperatures up to 150°C and 190°C, respectively. The presence of specific alloying elements results in different physical and metallurgical properties of new alloys as well as their solidification characteristics during the HPDC process, compared to AZ91D alloy. Hence, process parameters, such as melt and die temperature and injection profile, should be optimized. Furthermore, principles for proper die design, such as gate thickness and runners system, should be considered and addressed.
This paper presents design and process guidelines, in order to optimize the HPDC process of the above alloys and produce high performance components.
