主　　题：AZ31 magnesium alloy extrusion dynamic recrystallization 

摘      要：The effects of billet temperature on the maximum punch load,microstructure and mechanical properties of the extrusion of AZ31 cast magnesium alloy were *** is found that with the temperature decreasing,the microstructure of extruded sheets is more homogeneous and the grains become *** grain refinement does little effect on the strength of the material but significantly affects the *** the billet temperature is kept constant at room temperature,the elongation of the billets is up to 23%.The mechanical properties at extrusion direction(ED) and transverse direction(TD) were also *** differences of the properties between ED and TD are not obvious.
