摘　要: 本文研究了轴承钢在连续冷却条件下,加热温度直接影响奥氏体中残余碳化物的数量、分布和颗粒大小及最后球化组织的均匀性,观察了球化过程中碳化物的变化和析出规律,讨论了加热温度与分解温度和转变组织之间的关系。加热温度高低对球化组织程度和球化组织均匀性起主导作用。

Abstract: This paper describes the studies of bearing steel that heating temperature directly affects the amount,the distribution and the size of residual carbon in austenite,and the uniformity of the final spheroidizing structure,under the condition of continuous cooling,and the change of carbides and the law of precipitation was observed in the process of spheroidization,and the relationship was discussed between heating temperature and decomposition temperature and transformation structure. Heating temperature can play a leading role on the degree of spheroidizing and uniformity of spheroidizing structure.
Keywords: spheroidizing structure; carbide; austenitic; sorbite; eutectoid decomposition
