In-situ microstructure control by laser post-exposure treatment during laser powder-bed fusion

In-situ microstructure control is an important feature of laser powder-bed fusion (LPBF) that enables the tailoring of the mechanical behaviour of additively manufactured metallic parts. In this research, a novel method is introduced to control the formation of microstructure by laser post-exposure...
