摘      要：High temperature deformation behavior and workability of Mg-8.1 Gd-4.5Y-0.3Zr alloy were studied by compression *** equation with strain compensation and processing maps were *** results show that the activation energy Q,structure factor a,n and In A varies with the strain,its relationship fit well by fifth order *** flow stresses predicted by the extracted model are in good agreement with the experimental *** are five typical domains in the processing map,and the deformation mechanisms in different domains were determined by microstructure *** feasible processing window of the alloy is in the areas of 400-500℃/0.001-0.1 s^(-1).
