复合物、金属粉末成形体、烧结体的制造方法以及烧结体
摘要：
本发明涉及复合物、金属粉末成形体、烧结体的制造方法以及烧结体。金属粉末注射成形用复合物其特征在于，具有：二次粒子，其中第一金属粒子彼此结合；以及基质区域，包括第二金属粒子和粘合剂，第二金属粒子其构成材料与上述第一金属粒子相同、且平均粒径更小。另外，优选上述第一金属粒子的构成材料是Fe基合金、Ni基合金或Co基合金中任一种。另外，优选上述二次粒子是上述第一金属粒子彼此经由粘合剂结合而成的。
摘要（英）：

The invention relates to a compound, a metal powder molded body, a method for producing a sintered body and a sintered body. The compound for metal powder injection molding includes secondary particles in which first metal particles are bound to one another, and a matrix region including a binder and second metal particles composed of the same constituent material as the first metal particles andhaving a smaller average particle diameter than the first metal particles. It is preferred that the constituent material of the first metal particles is any of a Fe-based alloy, a Ni-based alloy, anda Co-based alloy. It is also preferred that in the secondary particles, the first metal particles are bound to one another through the binder.
