Phase Transformation Data
When you import phase transformation data, one phase transformation node is created for each of the phase transformations involved in the decomposition of austenite:
•
austenite to ferrite
•
austenite to pearlite
•
austenite to bainite
•
austenite to martensite
In addition to data that describe the phase transformation kinetics, other data is imported and added to each phase transformation node. They are:
•
phase transformation latent heat
•
the transformation-induced-plasticity (TRIP) parameter
The import can be performed under the Metal Phase Transformation, Austenite Decomposition, Austenite Decomposition, Kirkaldy–Venugopalan, Austenite Decomposition, Li–Niebuhr–Meekisho–Atteridge, and Alpha-Beta Phase Transformation interfaces, although the Austenite Decomposition interface is the most natural interface to perform the import from.
•
Note that you need to manually select the source phase and destination phase that participate in each imported phase transformation.
•
The imported diffusive phase transformations are based on TTT data from JMatPro®, and applicable phase transformation models in COMSOL Multiphysics are configured accordingly. In addition, the imported data is processed internally into a rate contribution that can be used without assuming an underlying functional form. The latter produces the best agreement across the entire range of imported data, and it uses the User defined phase transformation model.
