Perfectly dedicated to induction heat treating

Induction heat treatment simulation provides comprehensive information about temperature gradient from surface to core and also the location of areas where phase transformations occur. 

SIMHEAT® can monitor the impact of current frequency, coil geometry and even concentrators’ location within the heat affected zone. Material modelling takes considers electrical and magnetic properties that are temperature-dependent.

SIMHEAT® is perfectly dedicated to induction hardening with :

  • A multi-physics approach to capture ‘mechanical-electromagnetic-metallurgical’ phenomena

  • Monitor inductors & concentrators in motion to image rotating parts and induction equipment (e.g. case hardening of a crankshaft)

  • Up-to-date modelling of the generators that adjusts current intensity and frequency to maintain prescribed nominal power values

  • Prediction of heat affected zone and metallurgical transformations to identify austenized areas prior to quenching

  • Local mesh adaptation based on the temperature penetration depth

A series of innovative functionalities

SIMHEAT® has a lot of interesting features:

  • Full compatibility with JMatPro® database

  • Generation of Kirkaldy-based TTT diagram for low-alloy steel grades

  • Import tailored CCT diagram in text format

  • Carburizing: offset of transformation kinetics as a function of carbon rate

  • Age hardening based on Shercliff-Ashby models for heat-treatable aluminium alloys

  • Distortion models applicable to any kind of metal including aeronautic alloys

  • Material sensor tracking to plot characteristics over processing

  • Exhaustive results: temperature, phase transformation, HV or HRC hardness, distortion, residual stress, yield stress, carbon and nitrogen concentration, etc.

A fully integrated solution in the Transvalor suite

SIMHEAT_Transvalor_suite_EN

SIMHEAT® can be used as a standalone solution or in combination with Transvalor software. The perfect interoperability guarantees seamless results transfer from one solution to another.

It can be used with:

  • THERCAST®: for the simulation of foundry processes, continuous casting and ingot casting.

  • COLDFORM®: for the simulation of cold forming processes.

  • TRANSWELD®: for the simulation of welding processes and assembly.

  • DIGIMU®: for the simulation of microstructural evolution.

All the capabilities and functionalities of SIMHEAT® are also integrated in our FORGE® software, which is dedicated to the simulation of hot, semi-hot and cold forming processes.
