the results show that the phase transformation can be divided into two stages: 1) carbide-free bainite formed, which consists of the lath ferrite and carbon-rich austenite;
结果表明,可锻铸铁中的上贝氏体转变可分为两个阶段:转变初期形成无碳化物贝氏体;
after proper heat treatment the steel will have a dual phase structure of austenite and bainite. arranged alternatively in the form of lath ferrite and thin film austenite.
