Abstract

High-temperature sliding wear behavior of Cr₂B-, TiC-, and TiB₂-reinforced high-Mn heat-resistant alloys, as well as the base alloy, is thoroughly investigated at 1073 K, along with the underlying mechanisms. The superior high-temperature wear resistance of the particle-reinforced alloys is primarily attributed to the introduction of second-phase particles, which improves the hardness and stability of the glaze layer on the wear track surface and enhances the resistance to high-temperature plastic deformation of the substrate, leading to a reduction in the coefficient of friction and wear rate. The TiB₂-reinforced alloy exhibits the most exceptional high-temperature wear resistance. These findings provide a new strategy for the design of high performance wear- and heat-resistant alloys.

不同第二相颗粒强化的高锰耐热合金在 1073 K 下的高温滑动磨损行为

在 1073 K 下对 Cr2B、TiC 和 TiB2 增强高锰耐热合金以及基合金的高温滑动磨损行为及其机理进行了深入研究。颗粒增强合金具有优异的高温耐磨性，这主要归功于第二相颗粒的引入，第二相颗粒提高了磨损轨迹表面釉层的硬度和稳定性，增强了基体的高温塑性变形阻力，从而降低了摩擦系数和磨损率。TiB2 增强合金表现出最优异的耐高温磨损性。这些发现为设计高性能耐磨耐热合金提供了一种新策略。

期刊介绍： Materials Characterization features original articles and state-of-the-art reviews on theoretical and practical aspects of the structure and behaviour of materials. The Journal focuses on all characterization techniques, including all forms of microscopy (light, electron, acoustic, etc.,) and analysis (especially microanalysis and surface analytical techniques). Developments in both this wide range of techniques and their application to the quantification of the microstructure of materials are essential facets of the Journal. The Journal provides the Materials Scientist/Engineer with up-to-date information on many types of materials with an underlying theme of explaining the behavior of materials using novel approaches. Materials covered by the journal include: Metals & Alloys Ceramics Nanomaterials Biomedical materials Optical materials Composites Natural Materials.
