摘　　要：着重研究了铁的质量分数从0.85%变化到3.32%时对K418镍基高温合金的组织及性能的影响。研究表明,铁含量的变化,没有改变K418合金中主要相的组成,且铁含量对高温拉伸强度的影响较小。当铁的质量分数超过1%后,使材料的延伸率发生了波动,但波动幅度较小,并且这也可能是因为熔炼过程不均匀造成的。The influence of iron(0.85%-3.32%) on the structure and properties of K418 alloy is examined. The result shows that the main phase composition of K418 does not change with the amount of iron in alloy. Iron addition slightly influences the high temperature tensile strength. However, when the mass fraction of iron is more than 1%, the elongation fluctuates slightly, and it may be caused by the non-uniform distribution of composition during smelting.
