AS magnesium alloy series are used for high temperature applications that require adequate creep resistance. The aim of the present investigation was to obtain information regarding preparation procedure and phase constituents that are precipitated during solidification of AS21 and AS41 alloys and can affect the performance of these alloys in service conditions. Magnesium alloys are usually alloyed with manganese to remove iron. Hence, the understanding of the factors which influence the mutual solubility of Mn and Fe in molten magnesium is very important for establishing the efficient alloying procedure by Mn and other elements, particularly by Si in AS21 and AS41 alloys. Silicon is added to Mg-Al alloys in order to enhance the creep resistance. It was believed that only Mg2Si particles are formed through the solidification process of AS21 and AS41 alloys. However, it is evident from the results of present investigation that additional phases are present in the AS21 and AS41 ingots. The sequence of phase transformations occurring through the solidification process are discussed and the factors affecting the microstructure features were disclosed.
