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.
经适当热处理，获得贝氏体铁素体板条与奥氏体薄膜交替排列的奥氏体-贝氏体双相组织。
Experiments show that the dual phase structure suitable to wire drawing consists of fine ferrite islands dispersed in the matrix of lath martensite.
实验表明，适于拔丝的双相组织是在板条马氏体基体上分布着细小的铁素体岛。
The microstructure of the steel transforms from ferrite plus granular bainite, lath bainite plus lath martensite and then to lath martensite successively with the increasing of cooling rate;
随着冷却速率的增加，实验钢的显微组织由铁素体+粒状贝氏体逐步转变为板条贝氏体+板条马氏体及板条马氏体组织；
