| Abstract: | 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. |
