Abstract
A laser powder bed fusion (LPBF) of M789 ally steel has been carried out using an EOS M290 machine. The ideal orientations of M789 alloy were established using an electron backscatter diffraction (EBSD) technique. The analysis through ideal orientation and ODF analysis pointed out that as the heat treatment temperature is increased, the texture becomes strong. Analysis done through recrystallization map concluded that as the heat treatment temperature increases, the recrystallized grains increase which clearly explains the reason for strong texture at high temperature heat treatment. The results from this work can be used to control the texture of the M789 alloy to improve various physical and mechanical properties of the material.
