为了使高速钢粉末坯有效烧结到充分的密度，必须平衡粉末颗粒表面的氧化物和添加的正确数量的碳，因为烧结温度主要取决于氧化物被还原后的残余碳含量。本文介绍了从烧结实验中得出的基本关系。得出了实际构件烧结的结论，并与实际生产经验进行了比较。结果表明，碳控制不充分会导致致密化不完全和构件变形。介绍了切削刀片等烧结产品的性能数据。点/ 0342
To obtain effective sintering of high speed steel powder compacts to full density it is essential to balance the oxides present on the powder particle surface with the correct amount of added carbon, since the sintering temperature depends critically on the residual carbon content after the oxides have been reduced. In this paper the underlying relation-ships, derived from experimental sintering runs, are presented. Conclusions for the sintering of actual components are derived and compared with practical production experience. It is shown that inadequate carbon control leads to incomplete densification and to component distortion. Performance data for sintered products such as cutting inserts are presented. PM/0342
