Analysis of strain hardening behavior in a ductile Mg–Yb based alloy

A ductile Mg–Yb based alloy shows a larger strain hardening exponent of 0.45 than those of high-formable Mg alloys, suggesting better strain hardening ability and formability at room temperature. Hence we investigated the strain hardening behavior of the studied alloy under tensile mode. The studied alloy exhibits four strain hardening stages labeled as stage I, II, III, and IV from small to large strain, different from the majority of Mg...
