摘要：
Magnesium alloy’s creep stress exponent and creep mechanism at the room temperature were analyzed by TEM. Relationship among strain,stress and creep time was studied. The creep rate of some mechanisms were calculated. The results show that the dislocation mechanism is possible. The deformation mechanism is dislocation slipping on basal plane,and twinning improves creep deformation.
