摘    要：

研究金属粉末注射成形(MIM)铁基合金在强还原性氢气氛烧结条件下的合金化强化效果。结果表明，添加Cu、Ni、Mo等元素能取得显著的固溶强化效果，其中成分为Fe-2Ni-2Cu-0.45Mo的机械性能达到σ_b=483MPa，σ_s=340MPa，δ=9%和HRB83.

Abstract: Alloying strengthening for Fe-based alloys had been investigated, which prepared by metal powder injection moulding technology (MIM) and sintered under a strong reduction atmosphere. The results showed that the addition of Cu, Ni and Mo elements can make an appreciable solid solution strengthening, the alloy with composition of Fe-2Ni-2Cu-0.45Mo has mechanical properties as follows: σ_b =484 MPa, σ_s=340MPa, δ=9% and HRB83.
