The resolidification behaviour of the microsecond pulsed-laser-melted pool of pure bismuth as a function of grain size was studied using polarized light microscopy and X-ray diffraction. For single crystals and bicrystals, epitaxial regrowth is the dominant mechanism. For a mixed grain size, regrowth of larger grains dominates the microstructure and can result in the development of texture. Small grain sizes tend to inhibit the epitaxial growth at low-power density level. Formation of microtwins is predominant in the regrown regions when they are surrounded by fine grains.
