Abstract

The primary aim was to study the effect of laser shock peening at cryogenic temperature on spallation of FeCoCrNiCu high-entropy alloy. The spallation behavior at different shock velocities and temperatures was investigated by molecular dynamics simulation. The results indicated that the increase in shock velocity intensified the spallation phenomenon. Meanwhile, during laser shock peening process, the coupling effect of volume shrinkage and the inhibition of high-temperature softening effect generated by cryogenic temperature suppressed spallation occurrence, ultimately improving the spallation strength.
