Phase Transformations

This QForm module simulates phase transformations processes for alloys in the solid state, including steels, aluminum, nickel, and titanium alloys, with or without polymorphic transformations. It accurately predicts phase composition, mechanical properties (such as hardness and tensile strength), as well as residual stresses and strains during and after heat treatment.

Alloy phase transformation & heat treatment simulator

Fast simulation of various heat treatment variants to optimize cooling and heating conditions of a part in order to ensure the required properties, minimization of distortion and heat treatment time, energy-efficient production
Prediction of properties of finished forged pieces after heat treatment (hardness, ultimate strength)
Quenching cracks prediction option
Determination of the phase composition of a part
Evaluation of residual stresses and distortion after the heat treatment

The module supports flexible temperature profiles and sequences, allowing simulation of processes such as solution treatment, various quenching methods (interrupted, stepped, spray, isothermal, subcooling, self-tempering), tempering, and aging — including complex multistage treatments.

Simulation evaluates thermal stresses and distortion during heating and cooling, enabling assessment of cracking risks and precise prediction of the final forged part shape.

Simplify alloy data setup with the Alloy Generation Assistant

The Alloy Generation Assistant is designed for convenient input data setting: phase properties, phase transformation kinetics, latent heat, volume change coefficients during phase transformations, equilibrium volume fractions of phases. It is also possible to import material properties from other programs and reference books, such as JMatPro for low-alloy and carbon steels.

Prediction of phase transformations, phase composition of the workpiece, both at the deformation and heat treatment processes

Simulation options for diffusion and martensitic phase transformations at cooling and heating of material while accounting the latent heat of phase transitions and volume changes in the transformation process

The heat treatment module may be implemented for simulation of various production processes: quenching, tempering, annealing etc.
