0Zn, 0.7Zn, 1.5Zn, and 3.3Zn alloys are fully recrystallized after extrusion, with grain sizes of 7.9μm, 4.9μm, 5.9μm and 5.7μm respectively; as the Zn content increases from small to large, the maximum texture The structural strength has a tendency to increase first and then decrease. With the increase of Zn content, the tensile strength and yield strength of the hot-extruded alloy first increase and then decrease, while 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. The tensile strength, yield strength and elongation after fracture of the alloy are 369MPa, 305MPa and 18.5% respectively. The comprehensive mechanical properties of 0Zn alloy are second, and the comprehensive mechanical properties of 3.3Zn alloy are the worst.
