Simulation of heat treatment processes with FORGE®
Heat treatments are applied to forged components in order to improve final in-use properties. FORGE® embeds heat treatment capabilities to address multiple heat treatment processes: from austenitization to most common heat treatments, water or oil quenching including descente into the bath when applicable, spray quenching, induction hardening, carburizing, nitriding, tempering.
The heat treatment process chain can be simulated so as to obtain the final in-use properties. As an example, carburizing with subsequent quenching and tempering operation can be calculated, induction hardening followed by tempering.

FORGE® provides the prediction of:
- Distortion after quenching,
- Hardness, including hardness at the end of heat treatment workflow,
- Residual stresses,
- Metallurgic phases,
- Process parameters like quenching time to obtain optimal in-use propertie
- Full support of TTT and CCT curves to describe kinetic transformation,
- Various media conditions can be considered, including non-homogeneous heat transfer coefficient with ambient media
- With a unique software, forming operations and subsequent heat treatment ones can be simulated and can be chained.
