Abstract This study investigated the stress relaxation and fatigue life strength of laser-peened single-crystal nickel superalloy specimens compared to unpeened shot-peened following hot corrosion exposure then testing. The were treated by conventional laser peening a new cyclic plus thermal microstructure engineering process. latter treatment supports benefit unique process involving applicati...

The FeCoNiCrMo0.2 high entropy alloy coatings were deposited on BS960 strength steel by plasma spraying method with four different current intensities (250 A, 350 450 550 A). These then subjected to a subsequent micro-shot peening treatment. Surface characteristics including surface morphology, microhardness and phase composition characterized, the wear resistance of was assessed reciprocal fri...

The work aims to study the change rule of surface properties aluminum (Al) alloy after shot peening (SP), and obtain corresponding relationship between material characteristics SP parameters. Firstly, Finite Element Model (FEM) multi-projectile impact Al specimen was established by ANSYS/LS-DYNA (Version: Ansys15.0). Box-Benhnken design method (BBD) used 3-level 3-factor experiment with pressur...
