摘要：

The stress-strain behaviors of a Mg-2.8%Ce-0.7%Zn-0.7%Zr (wt.%) alloy with various strain rates at different deformation temperatures were investigated. It is found that the alloy can be extruded at 623 K with 90.2 = 222.4 MPa, sigma(b) = 257.8 MPa and delta = 12.0%. The working hardening, the dynamic recovery and the dynamic recrystallization play important roles to affect the plastic deformation behaviors of the alloy at different temperature regions, respectively.
