摘要
研究了4Cr5MoVISi钢表面激光快速熔凝后的显微组织和热疲劳性能。结果指出,表面激光熔凝组织对热疲劳裂纹的萌生和扩展有明显的抑制作用。
The microstructure and thermal stress fatigue property of 4Cr5MoVlSi steel subject to laser surface melting-solidifying were studied. The results showed that the laser surface melting-solidifying microstructure can inhibit the initiation and extension of thermal stress fatigue crack.
