摘要
采用力学性能测试、金相、X射线衍射、扫描电镜和透射电子显微分析对7A46合金型材的固溶-时效工艺、组织性能进行了研究。结果表明,这种合金适宜的固溶-时效制度为470℃/1h水淬,之后120℃/36h时效。在此条件下合金的抗拉强度、屈服强度和伸长率分别为450MPa、423MPa和14.0%。
The solution+aging processing,microstructure and properties of 7A46 alloy profiles were studied by mechanical properties test,OM,XRD,SEM and TEM techniques.The results show that the suitable solution+aging system of this alloy is water quenching at 470℃for 1h,then aging at 120℃for 36h.Under this conditions,the tensile strength,yield strength and elongation of the alloy are 450MPa,423MPa and 13.0%,respectively.
