本文对采用喷丸处理改善结构钢的短裂纹断裂性能进行了探讨。试验研究结果表明，通过适当的喷丸处理，结构钢的短裂纹断裂性能（裂纹扩展门槛值，裂纹扩展速率和疲劳寿命）可以得到具有较大实际意义的改善。
In this paper, the use of shot peening to improve the short crack rupture properties of structural steel are discussed. The experimental results show that the short crack rupture performance (crack growth threshold, crack propagation rate and fatigue life) of structural steel can be greatly improved by proper shot peening.
