Hot compression deformation behavior of Mg–Y–Zn alloys containing LPSO phase

The effect of the volume fraction of the long periodic stacking ordered (LPSO) phase on elevated temperature compressive deformation behavior is investigated using four types of Mg–Y–Zn alloys (Mg-0.4Y-0.2Zn, Mg–2Y–1Zn, Mg–5Y-2.5Zn, Mg–9Y–6Zn, where the numbers indicate at.%) produced by casting. The LPSO phase volume fraction is found to increase with increases in the concentrations of Y and Zn. The results obtained from compression tests at...
