Effects of Laser Multiple Processing on Properties of Heat-resistant Steel

摘要：

The heat-resistant steel after aluminized was treated by laser shock processing (LSP) with high power Nd:YAG laser, and then was tensile tested at 400℃. The effects of the high-temperature behavior after LSP were analyzed from residual stress and fracture organization. The results showed that the yield strength and tensile strength of heat-resistant steel after aluminized were improved obviously during the tensile testing at high temperature, and the High-temperature fatigue life of 00Crl2 with composite processing was enhanced vastly. Compared with the LSP, the High-temperature fatigue life of 00Crl2 heatresistant steel by aluminizing and LSP had a larger increase.
