进行了挤压态0Zn、0.7Zn、1.5Zn和3.3Zn合金时效实验，发

The aging experiments of extruded 0Zn, 0.7Zn, 1.5Zn and 3.3Zn alloys have been carried out. It is found that the alloy aging strengthening effect gradually decreases with the increase of Zn content, and the peak aging system corresponding to 0Zn, 0.7Zn and 1.5Zn alloys is obtained. 3.3 Zn alloy has no aging strengthening effect. The tensile strength and yield strength of peak-aged alloys first increase and then decrease with the increase of Zn content, while the elongation after fracture gradually increases with the increase of Zn content. The overall mechanical properties of 0.7Zn alloy are the best, and the tensile strength The strength, yield strength and elongation after fracture are 468MPa, 378MPa and 8.5% respectively. The high performance of the alloy benefits from the synergistic strengthening of the lamellar structure and β phase. The LPSO structure phase acts as the cathode of the corrosion microbattery during the local corrosion process, accelerating the corrosion and dissolution of the alloy matrix.

The time-called experiments of extrusion 0Zn, 0.7Zn, 1.5Zn and 3.3Zn alloys were carried out, and it was found that the relevant esophedic reinforcement effect of alloys decreased gradually with the increase of Zn content, and obtained the peak escapration system corresponding to 0Zn, 0.7Zn and 1.5Zn alloys, while 3.3Zn alloys had no esophic reinforcement effect. The pull strength and yield strength of the peak espresso alloy increased and then decreased with the increase of Zn content, while the elongation rate increased gradually with the increase of Zn content, the comprehensive mechanical performance of 0.7Zn alloy was the best, and the pull strength, yield strength and post-break elongation rate were 468MPa, 378MPa and 8.5 β%, respectively. The LPSO structural phase acts as the cathode of the corrosion microcryste in the process of local corrosion, accelerating the corrosion and dissolution of the alloy substate.

Aging experiments of as extruded 0zn, 0.7zn, 1.5zn and 3.3zn alloys were carried out. It was found that the aging strengthening effect of the alloys decreased gradually with the increase of Zn content. The peak aging systems corresponding to 0zn, 0.7zn and 1.5zn alloys were obtained, while 3.3zn alloy had no aging strengthening effect. The results show that the tensile strength and yield strength of the peak aged alloy increase first and then decrease with the increase of Zn content, while the elongation after fracture increases with the increase of Zn content. The comprehensive mechanical properties of 0.7zn alloy are the best. The tensile strength, yield strength and elongation after fracture are 468mpa, 378mpa and 8.5% respectively. The high performance of the alloy benefits from the synergistic strengthening of lamellar structure and β phase. The structure phase of lpso acts as the cathode of corrosion micro cell in the process of local corrosion, which accelerates the corrosion dissolution of alloy matrix.
