摘要
本文系统地介绍了作者所发现的渗入钢中稀土的表面效应及其作用;对固溶稀土所引起的空位浓度进行了计算和理论分析—为稀土催渗作用提出了理论根据;用热力学原理解释了稀土对钢中夹杂物的重构和变质作用。
the surface effect of rare earth penetrating in steel and its action found by authors is introduced. The consistency of voids produced by solid solution Re in steel has been calculated and analysed theoretically. We presented a theoretical basis for the effect of Re raising diffusion rate of boronising. The reconstruction and modification of Re to the inclusions in steel is explained.
