采用X射线衍射分析和残余应力测试方法研究了AISI 316不锈钢经喷丸和激光喷丸处理后的显微组织和残余应力。虽然这两个标本在深度方向上表现出相似的压缩残余应力分布，在SP标本的位错密度大于在LP标本，而在SP标本的微晶尺寸小于LP标本。因此，在样品中的微观结构特征的变化进行了两个过程不同。
Microstructure and residual stress in AISI316 stainless steels processed via shot peening (SP) and laser peening (LP) were evaluated using X-ray line profile analysis and residual stress measurements. Although both specimens exhibited similar compressive residual stress profiles in the depth direction, the dislocation density in the SP specimen was greater than that in the LP specimen, while the crystallite size in the SP specimen was less than that of the LP specimen. Thus, the variation in the microstructural features in the samples subjected to the two processes differed.
