摘要：

In this work Ti6Al4V powder was manufactured by the rotating electrode comminuting (REC) method to produce particles showing a spheroidal shape with an average size of 6.9 mu m. The influence of laser scan speed on density and mechanical properties was investigated. It was found that selective laser melting (SLM) technologies are capable of directly producing near to full density titanium alloy parts with line + microstructure. This fine and stable microstructure demonstrated high hardness and tensile strength with low elongation at break.
