| 摘 要： | 通过添加硅锰母合金,将硅、锰这两种对氧亲和力较高的元素加入到烧结钢中,以改善烧结钢的力学性能。结果表明,当硅含量为1.1%~1.7%,锰含量为2.7%,碳含量为0.35%时,烧结钢的强度可以超过800MPa。但添加硅锰母合金对冲击韧性有不利影响。两种不同成分的母合金相比较,硅、锰含量高的母合金对烧结钢的力学性能影响较显著。

| Abstract: | The SM master alloy was used to add high oxygen affinity elements Mn and Si into the sintered steel as alloying elements to improve the mechanical properties. The results show that the ultimate strength of sintered steel with 1.1%-1.7%Si,2.7%Mn and 0.35%C is above 800MPa. But the addition of SM master alloy has some deleterious effect on the toughness of sintered steel. By comparing the SM master alloys with two different compositions,the effect of SM master alloy with high content of Si and Mn is more remarkable. |
