超长时效对7075合金性能的影响 李杰1,赵坚1,宋仁国1,何源1,张宇1,陈小明1 (1.浙江工业大学,机械制造及自动化教育部重点实验室,杭州,310014) 摘要:利用洛氏硬度计,电子拉伸试验机,冲击试验机,扫描电镜(SEM),能谱仪(EDS)等设备对7075铝合金超长时间时效行为,力学性能,抗应力腐蚀性(SCR)及断口形貌进行了研究.结果表明,7075铝合金的硬度及强度都具有时效双峰特征.两个时效峰的硬度和强度相差不多,但对应第二峰时效的合金具有比较高的SCR性能.首次提出并运用"相变-Mg-H"复合理论解释了7075合金第二峰的高SCR性能现象. 关键词:7075合金; 超长时效; 组织; 性能; "相变-Mg-H"复合理论; 7075 alloy; over-length aging; properties; microstructure; "phase......
