强化相(硬质相)作为耐磨钢铁中的耐磨骨架,对耐磨钢铁的性能起到至关重要的作用。近年来,对于耐磨钢铁中强化相的实验研究,主要集中于耐磨钢铁中硬质相的形貌调控和力学性能上,对其热膨胀、热导率等热学性能没有全面的研究,并且硬质相的高温力学与热学性能基本为空白。总结了耐磨钢铁中强化相的研究现状和计算材料学在耐磨钢铁强化相研究中的应用,介绍了基于量子力学的第一性原理计算方法,从电子尺度上探究高铬铸铁和高速钢中合金元素对硬质相的结构、力学和热学性能的影响,并通过先进的微观结构表征和性能测试方法,将纳米尺度的原子电子行为与微米尺度的材料微观组织性能联系起来,从而有目的地选择和调控硬质相种类与性能,最终达成耐磨材料的成分设计和性能计算与实验相互统一。相关研究为建立耐磨钢铁中硬质相结构与性能数据库提供部分有价值的数据,为设计新型耐磨钢铁材料奠定基础。

As the wear resistant skeleton, strengthening phases (hard phases) play a vital role in the performance of the wear-resistant steels. In recent years, the experimental researches on the strengthening phases in the wear-resistant steels mainly focus on the morphology control and mechanical properties of the strengthening phases. There are no comprehensive researches on its thermal properties such as thermal expansion and thermal conductivity, and the high-temperature mechanical and thermal properties of the strengthening phases are basically blank. The experimental research status of strengthening phases in wear-resistant steels and the application of computational materials in strengthening phases are summarized. Firstprinciples calculations based on quantum mechanics are proposed to study the effect of alloy elements on the structure, mechanical and thermal properties of hard phases in wear-resistant steels from the electronic level, taking high chromium cast iron and high speed steel as research objects. The nano-scale atomic and electronic behavior is linked to microstructures and properties of micro-scale materials through advanced characterization methods. Therefore, the types and properties of hard phases could be selected and controlled purposefully. Finally, the mutual verification of composition design, performance calculation and experiment research of wear-resistant materials is achieved. The relevant researches provide some valuable data for establishing database of microstructure and properties of hard phases in wear-resistant steels, and lay a foundation for designing new wear-resistant steels materials.
