The results show that proper RRA heat treatment can improve SCC properties with retention of the high strength of T6 level. After pre-aging at 100 ℃ for 24 h, retrogression at 200 ℃ for 7 min, and reaging at 100 ℃ for 24 h, the ultimate tensile strength, yield strength and elongation of the alloy are 795 MPa, 767 MPa and 9.1%, respectively. Meanwhile the failure time of the alloy applied to tensile strength of 210 MPa in 3.0%NaCl+0.5%H2O2 corrosion condition is longer than 720 h. The corresponding TEM observation shows that after retrogression for 7 min and re-aging treatment, the microstructure of grain boundary is similar to that treated in the T73 condition with coarsen and isolated distribution, and the microstructure inside grain is similar to that treated in the T6 condition with small and homogeneous distribution.

研究结果表明：在峰值时效T6状态下合金强度高，但抗应力腐蚀性能差；采用合适的RRA热处理工艺既能使合金保持T6状态下的高强度的同时，又能显著改善合金的抗应力腐蚀性能；经回归7 min RRA处理后合金的晶界类似T73态析出相聚集粗化，而晶内类似T6态析出相细小弥散分布，在拉伸应力为210 MPa和3.0%NaCl+0.5%H2O2腐蚀液中，其断裂时间大于720 h，相应的抗拉强度、屈服强度和延伸率分别为795 MPa， 767 MPa和9.1%，显示优越的综合性能。
