Abstract The as--cast microstructure of Mg-based alloys containing Ca and Si was investigated using optical microscopy, XRD, SEM/EDS and TEM. It was found that the alloy containing low Si consisted of Mg-rich matrix and CaMgSi phase, while the alloy containing higher Si consisted of Mg2Si besides the Mg-rich matrix and CaMgSi. The phase CaMgSi existed in three different morphologies, namely discrete large angular, dispersive dot-like, and needle-like, while the Mg2Si, also needle-like, existed in the “Chinese-script” colonies. The formation mechanism of the as-cast microstructure was discussed in details based on a proposed pseudo-ternary Mg-Mg2Si-CaMgSi phase diagram.

Key words: Mg--Ca--Si alloy CaMgSi
