  3. Abstract:
  4. Cu-alloyed sintered steels are one of the main product groups in ferrous powder metallurgy (P/M). To expand the application of P/M technology to different sectors of industry and to create new market, it is believed that rapid prototyping and short serial production of sintered parts for functional testing is important. In the present work, rapid prototyping of sintered Fe-C-Cu steel powders by direct metal laser sintering (DMLS) process was studied. Fe, Fe-0.8%C, Fe-2%Cu, Fe-4%Cu, Fe-0.8%C-2%Cu-0.35%P powders were laser sintered in widely varying conditions. The densification and microstructural features of the sintered parts were evaluated. The results revealed that rapid prototyping of the investigated steels by DMLS process is feasible, i.e. the same level of density and mechanical properties compared with the conventional P/M route can be obtained using proper processing condition. This article briefly addresses the densification and microstructure features of laser-sintered Fe-C-Cu steel powders. © 2005 European Powder Metallurgy Association
