文摘

Metal injection molding (MIM) process of tungsten (W) and its alloys is investigated, including W, oxide dispersion strengthened (ODS) W, tungsten–copper (W–Cu) and tungsten heavy alloy (WHA). The ultrafine powder fabrication technology for W, ODS-W and W–Cu composite are presented, which is important for achieving the high sintered density and homogeneous microstructures. W powder developed with high flowability has been applied for MIM WHA. Wax-based binders have been employed for the feedstock fabrication, respectively. Some applications of the above materials are shown in this paper.
