| Abstract: | The effect of different deformation-aging treatments on the stress corrosion cracking of LY12 aluminum alloy was studied. The fracture surfaces and mic-rostructure of SCC specimens under different deformation-aging conditions were observed by means of SEM and TEM, and the reasons why the resistance of stress corrosion crack of LYl2 aluminum alloy is improved by deformation were discussed. |
