The kinetics of phase transformations in medium-carbon forging steels (MCFS) have been modeled based on CALPHAD multicomponent thermodynamics and the classical nucleation-growth theory. New treatments include the time dependency of parabolic growth rate of proeutectoid ferrite (α) , which account for the soft impingement effect by carbon enrichment in austenite (γ). And a potential transition o...

Non-uniform cooling conditions within a casting lead to locally differing microstructures, which result in locally differing mechanical properties. These have a tremendous impact on the behavior of the parts under their application load conditions and regarding their life time. The virtual development of castings can, therefore, only be effective when the process simulation is integrated into i...
