Densi fi cation of W – Ni – Fe powders using laser sintering

  title={Densi fi cation of W – Ni – Fe powders using laser sintering},
  author={Xuan Wang and Matthew Wraith and Stephen Burke and H. Rathbun and Kyle DeVlugt},
In this paper, Laser Sintering (LS) of 90%W–7%Ni–3%Fe (wt.%) powders have been investigated, with the goal to understand the influence of final density by laser power, scanning speed, laser trace width, and the number of scanning passes. The results suggest that the laser power and scanning speed are the most important factors influencing density; the influence of trace width and number of scanning passes are not significant. With the in­ crease of laser power and decrease of scanning speed… CONTINUE READING
