Watch our webinar: Reliable Simulation of Heat Treating Using CALPHAD-Based Tools
Some examples include:
- Calculate furnace gas chemistry based on composition, temperature and pressure, along with activity coefficients (such as activity of carbon, nitrogen, etc.) in the gas.
- Predict formation of precipitate phases within an alloy as a function of composition and temperature, along with the amounts of those phases and their compositions.
- Plot multicomponent phase diagrams, including Lehrer diagrams, for alloys that allow a quick overview of optimal regions for a heat treat process.
Diffusion module (DICTRA)
- Simulate the diffusion of carbon, nitrogen and boron in multicomponent alloys and predict the case depth profile, for example, as a function of time and carbon activity or carbon flux at the surface.
- Model the growth, coarsening and dissolution of precipitates (such as carbides in steels or Al2Cu in Al alloys).
- Predict the homogenisation of multi-component, multi-phase alloys including Ni superalloys.
- Model post weld heat treatment.
Precipitation module (TC-PRISMA)
- Simulate the concurrent nucleation, growth, dissolution and coarsening of precipitate phases as a function of alloy chemistry, temperature and time, during an isothermal / non-isothermal heat-treat cycle.
- Predict the fraction of precipitate phases and the number density and size distribution of the precipitates.
- Calculate TTT diagrams for precipitate phases.
