AbstractIn order to clarify martensite to austenite phase transformation mechanism of the steel ZG06Cr13Ni4Mo during tempering between A(s) and A(f) with low heating rate of 0.05 degrees C/s, a systematic study by dilatometer, XRD, TEM and EDX was carried out. The experimental results indicated that the reversed austenite generated during tempering was rich in Ni and did not have high density dislocation, which demonstrated the martensite to austenite phase transformation with low heating rate proceeded by diffusion. The reversed austenite generated over 600 degrees C would partially transform to martensite during subsequent cooling. One-stage tempering got the maximal amount of reversed austenite at 620 degrees C. Two-stage tempering system (620-660) degrees C + 600 degrees C could dramatically increase the amount of reversed austenite, because the new martensite transformed from unstable reversed austenite at first-stage tempering at 620-660 degrees C provided dispersive nucleation sites for the reversed austenite in the second-stage tempering at 600 V.
