摘要
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, an attempt has been made to improve the short-crack fracture characteristics of structural steel by the application of shot peening.The experimental results indicate that the short-crack fracture characteristics (the crack growth threshold, the crack propagation rate and the fatigue life)of structural steel can be improved substantially through an appropriate shot peening treatment.
