摘　　要：利用真空感应冶炼、SEM和EPMA等方法,对Ta在铁基合金熔炼中的溶解行为进行了试验研究。结果表明,高熔点纯金属Ta可以在铁基合金熔炼中溶解,适量Ta可以完全溶解于铁基金属中。真空感应冶炼含Ta铁基合金时,降低氧含量和增加精炼时间可以减少Ta的氧化烧损,促进Ta在铁基合金熔炼中的溶解。第3组元C、Cr可减少Ta的氧化烧损,但Cr的加入并不促进Ta的溶解。Solution behavior of tantalum(Ta)in the smelted Fe⁃based alloy was experimentally studied by means of vacuum induction melting as well as SEM and EPMA observations.The results show that Ta as an alloying element is dissolvable in the Fe⁃based alloy during melting process.An appropriate amount of Ta can be completely dissolved in Fe⁃based metals.When smelted Ta⁃containing Fe⁃based alloys by vacuum induction,reducing oxygen content and extension of refining time can reduce Ta oxidation damage and promote Ta dissolution in the smelted Fe⁃based alloy.It is analyzed that oxidation loss of Ta can be reduced by adding C and Cr.However,the solution of Ta cannot be improved when Cr is involved.
