Metal surface characterization by irradiation of an intense pulsed ion beam (IPIB) has been studied experimentally. The IPIB irradiation to metals leads to rapid heating of the surface which is immediately followed by rapid cooling and resolidification, resulting in metal surface modification. The intention is to focus on the formation of nanocrystalline phases and the reduction of machining roughness on a titanium surface. The experiments were performed with the pulse power generator HARIMA-II at Himeji Institute of Technology. The formation of nanostructured titanium by IPIB-irradiation is successfully demonstrated. The X-ray diffraction peaks of IPIB-irradiated titanium are broaden compared with that of non-irradiated titanium. The grain size of IPIB-irradiated titanium is estimated to be approximately 11 nm using Scherrer`s formula. The reduction of machining roughness on the titanium is estimated to be approximately 11 nm using Scherrer`s formula. The reduction of machining roughness on the titanium surface was also realized by IPIB-irradiation.
