摘　　要：本方研究了稀土元素对Cr-Mn-N铜性能的影响。试验得出,加入0.1％稀土元素能提高钢的抗氧化性,对钢的机械性能影响不大。试验钢种己成功地用于,1000℃下工作的炉用耐热构件。Their paper deals with the effect of rare earth elements on properties of a Cr-Mn-N heat-resistant cast steel. The results show that the addition of 0.1% are earth elements has improved the resistance to oxidation of the alloy by 10~15% until 1000℃ without sacrificing its mechanical properties. The alloy has successfully been made parts served at 1000℃ for long time。
