Mo2C/Ti64 composites with nearly full densification and enhanced tensile strength were developed by using laser powder bed fusion (LPBF). The addition of 1-3 wt% Mo2C particles with an average particle size of similar to 1 mu m enabled the LPBF-printed composites with an alternately laminated alpha&...
