Abstract
This research is devoted to study the effect of shot peening time with steel balls on mechanical properties of AA2024-T4 alloy. The test carried out using standard tensile specimens under various peening times (5, 10 , 15 , 20 and 30 minutes). Results showed an increase in yield and tensile strength values with increasing peening time up to 15 minutes where they were 355 & 505 MPa respectively. Also the strain hardening factor (n =0.26) and strength factor (k = 910 MPa) were maximum at this period of peening .On the other hand the maximum percentage of elongation was 22.7% obtained at 30 minute peening time .
