中文摘要:
      高锰钢是传统的耐磨材料。为进一步提升高锰钢的耐磨性能,使其能满足复杂工况的使用要求,本文采用凝固析出方法制备了不同体积分数TiC增强的高锰钢基复合材料,系统研究了复合材料的显微组织和磨料磨损性能。热处理后,复合材料由奥氏体和TiC两相组成,TiC颗粒均匀分布在高锰钢基体中,颗粒与基体界面清洁。磨料磨损实验表明,TiC颗粒的引入提高了复合材料耐磨性能。然而,复合材料的磨损性能随着TiC体积分数的增加而降低。研究表明这是因为随着TiC体积分数的提高,陶瓷粒径尺寸增大且部分形成团簇,陶瓷颗粒在磨损过程中发生破碎从而提高磨损率。
MICROSTRUCTURE AND WEAR PROPERTIES OF TIC-REINFORCED HADFIELD STEEL MATRIX COMPOSITES
英文关键词:Hadfield  Steel, TiC, Wear  Resistance Steel, Composites, Abrasive  wear
英文摘要:
      High manganese Hadfield steel is the conventional wear-resistant steel. In order to meet the requirements of complex working conditions, Hadfield steel matrix composites (SMCs) with various volume fraction of TiC were designed and fabricated using an in-situ solidification method. The microstructure and abrasive wear properties of these composites were examined. After heat treatment, the composites consist of austenite and TiC phases. TiC particles were uniformly distributed in the matrix, and the interface between the particles and the matrix was clean. It is found that the wear resistance of the composites can be improved by the introduction of TiC particles. However, with increasing TiC volume fraction, the wear resistance decreased slightly. We found the particle size increased and the particle segregations were formed with increasing TiC volume fraction. The increased wear rate with increasing TiC volume fraction was caused by the fracture of large particles.
