摘要
本文论述了 9SiCr钢中温 (35 0℃ )贝氏体组织的球化处理 ,在观察球化组织的基础上分析了它的主要特征和退火过程中组织转变的机理 。
This paper deals with the spheroidizing of medium temperature (350℃) bainite in 9SiCr steel.Based on the observation of spheroidized structure,the characteristics of spheroidizing and mechanism of structure transformation in globurizing are fully analyzed,and the influence of stepped heating on the medium temperature bainite transformation and its structural heredity are disussed as well.
