Abstract

A visualization method of metal grain boundaries with a short pulse laserhas been developed. This visualization method was required for selecting grain in local heating system with a CW(continuous wave)fiber laser for controllinggrain structures. Two kinds of short pulse lasers, nanosecond and femtosecond lasers, were used in the experiments for promoting the visualization. Thesample metal was a pure aluminum (99.59%) plate.The topography of the grain boundary regionswas changedbythe nanosecondlaser irradiation. This topography change enabled the visualization of the grain boundaries.
