时效对固溶+冷轧7075铝合金力学性能和显微组织的影响Effect of ageing on mechanical properties and microstructures of solution treated and cold-rolled 7075 Al alloy 采用拉伸测试、金相显微镜、XRD及TEM等方法,研究时效处理对经历固溶+冷轧的7075铝合金显微组织和力学性能的影响规律。力学性能测试表明:80、100、120 ...
Then microscopy was used to observe microstructure, and hardness test to mechanicalproperties.Theresults show that,after theenhanced solution treatment of465℃/30min+475℃/30min, the number and size of second-phase particles was decreasedhardly, grain’ size of alloy was finer, hardness higher, ...
Solution-treated 7075 Al alloy is subjected to equal-channel angular pressing (ECAP) and subsequent aging treatment. Fatigue crack growth (FCG) behavior of the samples in three different states was then evaluated, namely as-received, post-ECAP naturally aged and post-ECAP artificially aged. ...
