Özet:

 


In this work, cementite dissolution kinetics was
studied in 100Cr6 steel during partial and full austenitization. The change in
cementite volume fraction and size was determined from samples heat treated for
different durations at 840 °C and 1050 °C. The SEM micrographs were analyzed by
using ImageJ software to count size and volume fraction of carbides. The
obtained statistical data were used to draw the dissolution curves with a
nonlinear curve fitting method. It was found that the cementite dissolution
rate is fast at the beginning of partial and full austenitization. A model was
established and carbide dissolution was calculated using DICTRA software. The
dissolution curves were obtained and compared with the DICTRA simulations. The
calculation results are in good agreement with the dissolution curves from
statistical results of SEM micrographs. According to the calculation results,
the fast carbide dissolution is due to dissolution under non-partitioning local
equilibrium (NPLE) mode controlled by diffusion of C atoms and neglecting
diffusion of Cr.
