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.
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.
