*YEON Jaebong¹, NAKAMOTO Masashi¹, TANAKA Toshihiro¹ (1. Graduate school of engineering, Osaka university)

Keywords:surface fine crevice structure、microstructure formation、laser irradiation、scanning speed

We investigated the effect of laser scanning speed on the microstructure of laser irradiated metal surface, in order to understand the mechanism for the formation of surface fine crevice structure.
