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。
In this paper, the effects of rare earth elements on the austenite grain growth tendency of 60 CrMnMo steel were studied. The results show that rare earth significantly refined the austenite grains, austenite grain growth has a strong inhibitory effect. Also discussed the mechanism of action of rare earth elements.
