摘要: 综述了低合金马氏体耐磨钢的研究进展,主要涉及成分设计、热处理工艺及其对组织和力学性能的影响和耐磨性能等方面。成分设计主要采用少量多元的成分体系;热处理工艺有再加热淬火-回火处理、直接淬火-回火处理、亚温淬火-回火处理、淬火-配分处理和淬火-配分-回火处理等,通过控制组织形态及分布,实现硬度和性能的合理配合;耐磨性则通过调整化学成分、细化晶粒、优化轧制冷却工艺和适当的回火等得到改善。

Abstract: Research progress of low alloy martensitic wear-resistant steel was reviewed, mainly involving composition design, heat treatment process and its on microstructure and mechanical properties, and wear resistance. Composition design mainly adopts a small number of multi-component system, heat treatment processes include reheat quenching-tempering treatment, direct quenching-tempering treatment, subtemperature quenching-tempering treatment, quenching-partitioning treatment and quenching-partitioning-tempering treatment. By controlling the structure shape and distribution, the hardness and toughness can be matched reasonably. The wear resistance is improved by adjusting chemical composition, refining grain, optimizing rolling cooling process and proper tempering.

Key words: low alloy martensitic wear-resistant steel, chemical composition, heat treatment process, microstructure, mechanical properties, wear resistance
