Role of ultrasonic shot peening on low cycle fatigue behavior of 7075 aluminium alloy

•Nanostructures was developed in surface regions of 7075 Aluminium alloy from USSP.•There was no phase transformation in the alloy from the USSP.•Maximum compressive residual stress was found to develop at sub-surface region.•Pronounced enhancement in LCF life resulted from the USSP treatment. Ultra...
