摘要：In this work, constant and increasing temperature fatigue interaction effect on fatigue behavior of 2017-T4 aluminum alloy was investigated and the effect of wet shot peening on this alloy was also studied. Fatigue tests at constant load constant temperature and constant load increasing temperature were performed. The constant temperatures were RT (25 ̊C) and 100 ̊C. While the increasing temperatures were RT, 50 ̊C, 100 ̊C and 150 ̊C for one test program. The constant fatigue properties of the increasing temperatures were observed the worst case compared to the others constant fatigue properties. Fatigue strength at 100 ̊C was reduced by 10.43 % compared to (RT) fatigue strength, while the wet shot peening (WSP) reduced the above reduction percentage from 10.43 % to 8.69 % i-e an improvement of about 2% was observed Shot peening constant fatigue constant temperature (100 ̊C) revealed that an improvement in the fatigue properties was obtained i-e fatigue life by 1.94 % and fatigue strength by about 2 %.
