Compression tests of a Mg-13Gd-4Y-2Zn-0.5Zr alloy were carried out on Gleeble-1500D thermo-mechanical simulator within temperature range 420–500 °C and strain rate 0.001–5 s–1 so that the corresponding flow behavior was investigated. The Zener-Hollomon parameter Z used in hyperbolic-sine-type equation to express relationships between peak stress, deformation rate. Work hardening, dynamic recove...
