Abstract:

Evolution of the microstructure of a steel 120G4 after pearlite transformation and subsequent heating to temperatures of 680-1200 degrees C has been investigated by transmission electron microscopy. It has been established that with a rise in the heating temperature the fraction of the carbide phase decreases and the austenite defect structure changes from microtwins and stacking faults to dislocations. Upon heating to T = 700-720 degrees C, in the restored (reverted) austenite, wide twins with a regular crystallographic faceting, whose appearance is seemingly connected with the specific features of the pearlite transformation rather than with relaxation of internal stresses, have been discovered experimentally for the first time.
