| Abstract: | The aging treatment at 100～220℃ for ZK60 magnesium alloys were carried out, through analyzing microstructure, fracture scanning and testing of mechanical properties. The influences of aging temperature on microstructures and mechanical properties of ZK60 magnesium alloys were researched. The results show that the microstructures and mechanical properties of ZK60 alloy significantly improve by aging treatment. Mechanical properties get regularly changed with aging temperature increasing. Network structure is the main reason of the changes in mechanical properties. The optimum aging temperature of ZK60 alloy is 190℃. |
