Abstract
Austenite containing fine particles of carbides may undergo the eutectoid transformation by either the pearlite reaction or the divorced eutectoid transformation (DET) reaction. The latter reaction automatically produces a spheroidized structure, while the pearlite reaction produces a structure that resists spheroidization. This study has evaluated the heat treatment conditions that promote the DET in 52100 steel. The results show that the DET is dominant over the pearlite reaction for austenitization at temperatures of 830 °C and below and for cooling rates of 500 °C/h and below. This information should be useful in the design of more energy efficient heat treatment processes for spheroidization annealing than the very long time processes currently recommended in the literature.
