- We prepared Cr-Mn-N stainless steel sample by directional solidification technique, analyzing solid-liquid interface solute distribution of different composition and the pull-speed quantitatively with Energy Disperse Spectroscopy. The experimental results indicate that Cr element equilibrium distribution ratio of the sample without the addition of rare earth is less than 1, Mn and Ni elements close to 1. When the withdrawal rate is 12 m/s, the distribution ratio of Cr element increases and Mn and Ni elements equilibrium distribution coefficient decreases with the increase of Ce. When sample is not added rare earth, Cr element enriches in the solid-liquid interface, Mn element shows a decreasing trend, small change in Ni element. When the rare earth content is 0.002%, Cr element gathers in solid-liquid interface, Mn element reduces, the change of Ni element is not great. When the rare earth content increases to 0.067%, Cr element reduces in the solid-liquid interface, Mn and Ni elements increase.
