Effect of laser power on defect, texture, and microstructure of a laser powder bed fusion processed 316L stainless steel

The effect of laser power on defect characteristics, microstructure development, constituent phases, and crystallographic texture was studied on a laser powder bed fusion (L-PBF) processed 316L stainless steel. A series of specimens was additively manufactured as a function of laser power ranging from 380 to 200 W with a fixed scan speed of 300 mm/s. The density, size, shape, and orientation of pores in as-printed L-PBF cylinders were...
