在最佳变形条件下，开展了0Zn、0.7Zn、1.5Zn和3.3Zn合金

Under the optimal deformation conditions, the extrusion experiments of 0Zn, 0.7Zn, 1.5Zn and 3.3Zn alloys were carried out. It was found that the alloys were completely recrystallized after extrusion, and the crystals of 0Zn, 0.7Zn, 1.5Zn and 3.3Zn alloys The grain sizes are respectively 7.9μm, 4.9μm, 5.9μm and 5.7μm; with the increase of Zn content, the maximum texture strength increases first and then decreases; the tensile strength and yield strength of the alloy increase with the increase of Zn content First increase and then decrease, but the elongation after fracture does not change significantly with the increase of Zn content. The overall mechanical properties of 0.7Zn alloy are the best, with tensile strength, yield strength and elongation after fracture of 369MPa, 305MPa and 18.5% respectively. .

Under the optimal deformation conditions, the extrusion experiments of 0Zn, 0.7Zn, 1.5Zn and 3.3Zn alloys were carried out, and it was found that the extrusion of the alloys were all fully recrystimulation tissues, 0Zn, 0.7Zn, 1.5Zn and 3.3Zn alloys with grain sizes of 7.9 m, 4.9 m, and 5.9 m and 5.7 m; with the increase of Zn content, the maximum weaving strength has the tendency to increase first and decrease later; the anti-pull strength and yield strength of the alloy increase and decrease with the increase of Zn content, and the elongation rate after break 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 369MPa, 305MPa and 18.5%, respectively.
