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.
