WebThe survey of divorced pearlite in higher Mn bearing steel was carried out through scanning electronic microscope following isothermal transformation heat treatment. The results show that while divorced transformation taking place in the higher Mn bearing steel just slightly below A1, the cementite could be produced in such way as growing on ... Webaustenitization and divorced pearlite transformation [4]. Three cycles are sufficient for complete spheroidisation of lamellar pearlite. Austenitization is in ASR process rapid, performed by i.e. induction heating in rate in order of tens degree per second. Ferritic matrix is austenitized and cementite lamellae only partially dissolved [5, 6]. WebOne method of achieving this economically is togenerateamicrostructure known as divorced pearlite, in which ferrite and cementite grow from the austenite in a non–cooperative manner, leading to a final microstructure which consists of coarse, spherical particles of cementite dispersed in a matrix of ferrite.
