Abstract The samples manufactured by the elastic alloy 3J58 were tested by laser shock waves,and the nano-indentation experiments were made by Triboindenter in Hystron Company,and residual stresses were determined by using XRD with sin2 ψ method.The results show that surface residual stress distributions,nano-hardness and elastic modulus in the shocked region and the laser-affected region are clearly improved,which contributes to an increase in the surface properties in the near surface of the samples manufactured by the elastic alloy 3J58.
