During conventional tool-steel production, the steel is cast and then forged in the ideal temperature window of 1100–1200 °C. At these temperatures the metastable M 2 C carbide phase transforms into other, more stable, carbides. The reports in the literature indicate that the M 2 C carbides transform to M 6 C and MC carbides following the ...

In order to simulate the dissolution process for bulk carbides having complex morphology, the micrograph of the bulk carbide shown in Fig. 1 was discretized and digitized. Since the time required for the dissolution of the carbide was much longer than the austenitizing time of pearlite [18, 19], it was assumed that the pearlite instantaneously …
