Effect of reinforcing phase inherited from another composite on the mechanical properties of cast magnesium base composite

► Processing in-situ Mg-base composite by dissolving Al-base composite in Mg. ► Brinell hardness has increased with increased quantities of reinforcing phases. ► Brinell hardness has decreased gradually with increased processing temperature. ► The tensile properties in the composites have decreased with increased porosity. ► The tensile properties have decreased with increased particle content.
