Comparisons of microstructure, thixoformability and mechanical properties of high performance wrought magnesium alloys reheated from the as-cast and extruded states

•Reheating from the extruded alloy is shown to produce ideal semi-solid structures.•The as-cast alloy exhibits non-uniform microstructures.•The as-cast alloy is not as thixoformable as the extruded alloy. The solid grain size, degree of spheroidization, contiguity and practical liquid fraction of Mg...
