Influence of Plastic Deformation Degree on Microstructure and Mechanical Properties of the Magnesium Alloy ZK60 after T5 Treatment

Jianmin Yu; Zhi Min Zhang; Bao Hong Zhang; Qiang Wang

The effects of extrusion ratios (15, 30, 45and 60) on microstructure and mechanical properties of ZK60 magnesium alloy after T5 treatment were investigated. The results show that mechanical properties increase with the increase of extrusion ratios from 15 to 45.However, when the extrusion ratio is increase to 60, each mechanical property is decreased severly.By comparison,in the extrusion ratio of 30, ZK60 magnesium alloy after T5 treatment has excellent comprehensive mechanical properties.Different degrees of dynamic recrystallization appeared in the extrusion process and induced precipitation of second phase.The precipitation of the second phase is beneficial to the grain refinement and meanwhile to the promotion of the strength.
