In hypoeutectic Mg-Al-based alloys, Mg17Al12 forms in the last stages of solidification by a eutectic reaction that is usually fully or partially divorced. Here we investigate nucleation, growth and morphology Mg17Al12-containing multicomponent Mg-9Al-0.7Zn-0.2Mn alloy. Under all conditions studied, formed an interconnected skeleton 3D orientation domains spanned multiple α-Mg grains, indicatin...
