Abstract The traditional approach to improving the abrasion wear resistance of martensitic steels is to increase their hardness via high carbon levels. However: (i) a higher hardness is usually accompanied by a lower toughness, negatively affecting the impact wear resistance, and (ii) increased carbon concentrations reduce weldability and complicate thermal cutting. This work explored microalloying with Ti as a method to simultaneously increase hardness and toughness via a concurrent precipitation of coarse TiMoVCN, fine TiC and fine Fe3C particles.

与钛合金化的马氏体耐磨钢

摘要 提高马氏体钢耐磨性的传统方法是通过高碳含量来增加其硬度。然而：(i) 较高的硬度通常伴随着较低的韧性，对冲击耐磨性产生负面影响，以及 (ii) 增加的碳浓度会降低可焊性并使热切割复杂化。这项工作探索了用 Ti 进行微合金化作为一种​​方法，通过同时析出粗 TiMoVCN、细 TiC 和细 Fe3C 颗粒来同时提高硬度和韧性。五板钢含
