Kinetics of the formation of the carbide network in steel ShKh15

1. We studied the kinetics of carbide network formation under isothermal conditions and plotted diagrams characterizing the formation of the carbide network with time and temperature. 2. An increase of the carbon and chromium concentrations in steel ShKh15 accelerates the formation of the carbide network and broadens the temperature range in which it is formed; carbon has a stronger effect than chromium. 3. Additions of vanadium and tungsten (0.25–0.49%) and molybdenum (0.13–0.48%) slow down the formation of the carbide network in steel ShKh15. Molybdenum has the greatest effect, and in this case the hardenability of the steel increases.
