- 摘要:Aging behavior and related microstructural evolution of AZ80-Ag alloy as a function of aging temperature are systematically investigated. Results show that Ag addition can significantly enhance the age-hardening response of AZ80, improving its peak hardness and shortening the time to reach the peak simultaneously. Two kinds of continuous precipitates and three kinds of discontinuous precipitates are observed under varying conditions. The volume fraction ratio of continuous precipitates to discontinuous precipitates increases with increasing aging temperature. When aged at 175 degrees C for 38 h, the whole microstructure is invaded by discontinuous precipitates and an ultimate tensile strength of 428 MPa is achieved.
