Computational phase equilibria and experimental investigation of magnesium-aluminum-calcium alloys

► New understanding in the phase equilibria of Mg-Al-Ca system. ► Clarified the role of ternary (Mg,Al)2Ca phase in creep of Mg-Al-Ca alloys. ► Calculated Ca/Al composition ranges suppressing the formation of Mg17Al12 phase. ► Scheil simulation results agree with high-pressure die casting microstructure.
