The results show that the surface layer hardness and bulk yield strength of the steel sheet increase obviously when the SMAT time is 5 minutes , however , no such increasing is observed for continuously increasing SMAT time .
表面机械研磨处理时间对性能的影响并非线性增加，表面硬度和整体材料的屈服强度在处理5min时增加显著，处理时间继续增加到15、30和60min，它们的增加速度很小。
