| 摘 要： | 研究了Zr对Al-Zn-Mg-Cu合金显微组织和力学性能的影响。结果表明,添加少量Zr可以细化合金铸态组织,并且在热挤压过程中抑制再结晶。在固溶时效过程中,可以促进第二相粒子的析出,从而使基体中析出均匀弥散第二相粒子。T6状态下,未加Zr的合金其抗拉强度仅为600MPa,伸长率为10.5%;而加Zr后其抗拉强度超过650MPa,伸长率达到12.3%。

| Abstract: | Effects of Zr on microstructure and mechanical properties of Al-Zn-Mg-Cu alloy have been investigated. It was found that minor Zr addition can refine the as-cast microstructure of alloy and inhibit the recrystallization during hot extrusion. In addition, it can promote the segregation of uniform disperoids in solid solution treated alloy. The tensile strength and elongation of the T6 treated alloy without Zr and with Zr addition are 600 MPa, 10.5% and 650 MPa, 12.3% respectively. |
