Abstract

The pearlite formed in 100Mn13 high carbon high manganese steel after 1323 K water toughening subsequently 923 K aging treatment is studied by transmission electron microscope and high-resolution technique. The results show that the pearlite is composed of three phases, which are M3C lamellae, M7C3 lamellae, and ferrite lamellae, respectively, with the orientation relationships of ( )α∥( )M7C3, ( )α∥( )M3C, ( )M3C∥( )M7C3, [ ]M3C∥[ ]M7C3∥[ ]α. And M7C3 is formed at the phase interface between M3C and α. The growth physical model of three-phase pearlite is proposed.

时效100Mn13钢中三相珠光体的形态与形成

采用透射电镜和高分辨率技术研究了100Mn13高碳高锰钢经1323k水增韧后923k时效后形成的珠光体。结果表明:珠光体由M3C片层、M7C3片层和铁素体片层组成，取向关系为()α∥()M7C3、()α∥()M3C、()M3C∥()M7C3、[]M3C∥[]M7C3∥[]α。M7C3形成于M3C与α的相界面。提出了三相珠光体的生长物理模型。
