摘要: 讨论了棒形钢试样的疲劳寿命与激光辐照参量、硬度、层深间的关系。

关键词: 激光, 钢试样, 疲劳寿命

Abstract: It is discussed in this paper that the fatigue life of bar steel specimens is related to the laser radiation parameters, hardness and surface layer deepness. Furthermore, the mechanism of microstructure of No. 45 steel is analysed.

Key words: laser, steel specimen, fatigue life
