Shot peening is also improved the stress relaxation ability of copper alloy.

喷丸处理亦能改善铜合金的应力松弛性能。

Crack initiation life is much longer than those of low shot peening pressure.

低喷丸强度试件表面微裂纹大量萌生，密度非常高。

The SCCR could be further improved by promptly polishing the surface after shot peening.

若喷丸强化后再表面磨光，则可以进一步改善喷丸强化提高SCC抗力的效果。

Mechanic shot peening is a traditional process and widely employed by industrial circles.

传统的机械喷丸工艺在工业界已经得到广泛的应用。

The surface residual stresses of the rolled workpieces can be reduced remarkably by shot peening.

滚压后再喷丸显著降低工件的表面残余压应力。
