AbstractThe present work devote the effect of shot peening time on the mechanical properties for two aluminum alloys AA2017-T4 and AA6063-T5. The test carried out using standard tensile specimens under various shot peening times. The results showed that the increase in yield and tensile strength values. The maximum increasing at 15 minute for AA 2017-T4, and at 9 minute for AA 6063-T5. The maximum values of strain hardening factor (n) and strength factor (k) are recorded at 15 minute for AA 2017-T4 while recorded the maximum values of (n) at 24 minute and (k) at 9 minute for AA 6063-T5. The results showed that the percent elongation are increased to maximum value at 9 minute for AA 2017-T4 while the minimum value was at the same time for AA 6063-T5.
