چکیده انگلیسی
The effects of retrogression and re-aging treatment on the intergranular corrosion behavior of Al-5.0Mg-3.0Zn alloys are systematically studied. The alloy's strength increases when retrogression temperature increases from 390â¯Â°C to 420â¯Â°C. Samples retrogressed at 390â¯Â°C then re-aged are very susceptible to intergranular corrosion and those retrogressed at 405â¯Â°C and 420â¯Â°C express good corrosion resistance. Then the alloy's corrosion susceptibility rises with increasing retrogression temperature. Grain boundary precipitates are coarsened and distributed discontinuously with decreasing retrogression temperature. Higher retrogression temperature results in higher Mg and Zn content difference and intergranular corrosion susceptibility.
