摘要本工作主要研究了不同均匀化工艺对大规格7075铝合金铸锭组织的影响以及对轧制薄板性能的影响。研究结果显示:合金的铸态组织主要由Al基体+Mg(Zn,Cu)₂相非平衡共晶相组成。465 ℃/24 h均热后,合金中枝晶组织部分消失,低熔点相溶解不充分。465 ℃/24 h+478 ℃/8 h均热后,共晶组织基本消除,残留相主要是难溶解的含Fe相,均匀化效果优异。通过将不同均热后铸锭轧制成薄板,二级均热后的薄板T6态力学最优,抗拉强度为533.5 MPa,屈服强度为455 MPa,延伸率为16.5%。

Abstract: The effects of different homogenization processes on the microstructure of 7075 aluminum alloy ingot and the properties of rolled sheet were studied in this paper. The results show that: the as-cast structure of the alloy is mainly composed of Al matrix+Mg(Zn, Cu)₂ phase non-equilibrium eutectic phase. After homogenization at 465 ℃/24 h, the dendrite structure in the alloy partially disappeared, and the low-melting point phase was not fully dissolved. After 465 ℃/24 h+478 ℃/8 h homogenization, eutectic structure is basically eliminated, and the residual phase is mainly the rich-Fe containing phase, with excellent homogenization effect. After different soaking ingot is rolled into thin plate, the T6 state mechanics of the two-stage homogenization is optimal, with tensile strength is 533.5 MPa, yield strength is 455 MPa and elongation is 16.5%.
