You must include a parameter table of type "ABQ_PHASE_TRANS_Diffusional_TTT_Constants" in the material definition to specify the constants for the time-temperature-transformation (TTT) diagram for a diffusional transformation whose input option is set to TTT in the parameter table of type "ABQ_PHASE_TRANS_Transformations".

The parameter table must have a unique label of "ABQ_PHASE_TRANS_Trans_NameOfTransformation_TTT_Constants", where NameOfTransformation is the name of the transformation defined in the parameter table of type "ABQ_PHASE_TRANS_Transformations".

The parameter table of type "ABQ_PHASE_TRANS_Diffusional_TTT_Constants" can define only one set of data.

Parameters

Starting Proportion
Relative total volume fraction of child phases at the start of the transformation. This value must be between 0 and 1.
