部分扩散铁基合金粉末的压缩性及烧结均匀化

COMPACTIBILITY OF PARTIALLY DIFFUSION-ALLOYING IRON-BASED POWDERS AND THEIR HOMOGENEITY AFTER SINTERING

摘要: 研究了（%）Fe-1.5Cu-2Ni、Fe-7MC、Fe-2Cu-0.6P部分扩散粉末（分别混入碳）试样的压缩性、烧结均匀化程度、机械性能等。实验结果表明:部分扩散粉末具有较高的压缩性,同时也有较好的烧结均匀化性能,烧结后铜、钼、磷等元素得到较均匀的分布。上述三种材料的烧结态强度分别为500、600和700 N/mm²。

Abstract: Compatibility, homogeneity and mechanical properties, etc. of assintered specimens made from partially diffusion-alloying powders of Fe-1.5 Cu-2 Ni, Fe-7 MC and Fe-2 Cu-0.6 P（mixed with carbon respectively） have been studied. It demonstrates that partially diffusion-alloying powders possess superior compactibility as well as sintering homogeneity. After sintering distribution of copper, molybdenun and phosphorus etc. elements was very homogeneous. The strength of above three as-sintered materials is 500、600 and 700 N/mm² respectively. MC is iron-base master alloy containing Mo, Cr and C.
