Divorced Eutectoid Transformation in the Spheroidization of Bearing Steels

Source

Using dilatometry, it was possible to follow the various phase transformations encountered while spheroidizing-annealing bearing steels. A steel with 0.67 wt% carbon has been considered in the present study, as an example, where the starting microstructure was tough-tempered martensite. In addition, the widely used bearing steel 100Cr6 was investigated as a reference. The aim of the work was to focus on the austenite transformation into divorced pearlite in an attempt to optimize currently employed spheroidizing-annealing heat treatment schedules.
