Some examples include:
- Determining the heating temperature required prior to forging to solutionise the alloy and the re-heating temperature for final forging or rolling.
- Establishing composition ranges which give the widest precipitate free austenite single region over the widest range of temperatures possible. For alloys with no austenite single region, evaluating how the chemistry of the alloy could be modified to give such a region.
- Predicting formation of precipitate phases within an alloy as a function of composition and temperature, along with the amounts of those phases and their compositions.
- Plotting multicomponent phase diagrams for alloys that allow a quick overview of optimal regions for a heat treat process.
Diffusion Module (DICTRA)
- Simulating the solutionising kinetics; the time required to dissolve precipitates into the solution phase. Establishing the sensitivity to both chemistry of the alloy and temperature as well as the sizes of the precipitate phases.
Precipitation Module (TC-PRISMA)
- Finely solidified primary precipitate phases can be controlled to remain fine by controlling the heat treating temperature prior to forging and re-heating temperature for final forging or rolling. The Precipitation Module can be used to simulate the changes in size distribution as a function of chemistry and temperature and time to establish the sensitivity of the precipitate size distribution to these parameters.
