Evaluation of microstructures of peening processed austenitic stainless steel using X-ray line profile analysis

Kumagai, Masayoshi*; Akita, Koichi; Imafuku, Muneyuki*; Oya, Shinichi*

Microstructure and residual stress in shot and laser peened AISI316 stainless steels 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 hardness and dislocation density on the two specimens were different. The hardness of the SP specimen was greater than that of the LP specimen. And the dislocation density in the SP specimen was greater than that in the LP specimen. Thus, although the residual stress profiles of both SP and LP specimens were similar, the microstructural features in the samples differed.
