摘　　要：研究了细晶无磁硬质合金金属注射成形工艺中碳含量的控制。发现了亚微细晶硬质合金易于增碳的趋势和粘结剂脱除的残留碳是导致合金增碳的主要原因。开发了消除烧结增碳缺陷的工艺,使合金达到了优异的力学性能。CarbonControl in MIM Process of Nonmagnetic Fine cemented Carbide was studied. It was found and proved that the residual carbon after debinding makes carbon pice-up in fine-cemented carbide. The carbon pick-up was successfully overcome and the final sintered MIM parts of excellent mechanical properties were produced.

关 键 词：金属注射成形 硬质合金 碳含量
