摘　　要：对一种新型中高碳贝氏体钢的组织、转变动力学和耐磨性进行了研究。中高碳贝氏体钢空冷后的组织为贝氏体、马氏体、碳化物和残留奥氏体，组织细小均匀。大截面实物硬度测定和组织观察表明，截面上具有高硬度，并组织分布均匀。中高碳贝氏体钢具有高的耐磨性。The microstructure , transformation kinetics and wear resistance of a new category of medium-high carbon bainite steel has been investigated . The microstructure consists of bainite ,martensite ,carbide and retained austenite. The microstructure is fine and uniform. The hardness test and microstructure observation on the specimens with large cross-section has shown that the medium-high carbon bainite steel possesses high hardness and high wear resistance in whole cross-section.
