研究了预形变和时效对2091合金抗应力腐蚀性能的影响.结果发现,合金在预冷轧1%,并经170℃×5h的时效后不仅具有较高的强度,而且伸长率出现峰值,同时具有最佳的应力腐蚀抗力.对各种状态的合金进行了微观组织分析.
The effects of pre-deformation and aging on the stress corrosion resistance of 2091 alloy were investigated.The results show that the alloy has not only high strength but also high elongation after 1% pre-cooling and aging at 170 ℃ for 5h, At the same time, it has the best stress corrosion resistance.Micro-structure analysis of the alloys in various states.
