摘　　要：本文研究了稀土元素对60 CrMnMo钢奥氏体晶粒长大倾向的影响。结果表明,稀土显著细化了奥氏体晶粒,对奥氏体晶粒长大有强烈的抑制作用。同时还探讨了稀土元素的作用机理。The influence of RE addition on the tendency to austeniticgrain growth in 60CrMnMo steel is investigated. Experimentalresults indicate that RE addition not only fines the austeniticgrains, but also restrains the austenitic grain growth. Themechanism related is also discussed.

关 键 词：稀土元素 奥氏体晶粒度 晶粒长大
