The most suitable condition that the fine crystal layer is produced and influence of the fine crystal layer on fatigue strength of SCM415 are examined. Generation of the fine crystal layer by FPB processing and the SP processing is reported in the past study. However, only a surface small portion can generate the fine crystal layer. In addition, it is hardly examined the influence that the fine crystal layer on fatigue strength. In this study, the most suitable condition that the fine crystal layer was produced throughout the surface was examined first. As a result, it was understood that strain rate and a projection rate influenced generation of the fine crystal layer. From this, it is thought that it is easy to generate fine crystal layer by lengthening projection time in small projection materials.
