摘要
本文研究了加稀土5%Mn钢的热处理、组织和机械性能,探索其部分代替9Ni钢使用于-196℃的可能性,并以同样成分的无稀土钢作为对比,研究稀土在该钢中的作用。
The heat treatment, mcirostructures and mechanical properties of 5% Mn steel containing Rare Earth Elements (RE) are studied. The purpose is to explore proper technology by which the steel may meet ciyogenic strength and toughness(-196C) requirments of 9 % Ni steel For the sake of investigation of the effect of RE a steel without the addition of RE is also tested.
