ABQ_PHASE_TRANS_Diffusional_JMA_Coefficients

You use this property table type to specify the coefficients of the Johnson-Mehl-Avrami (JMA) model for a diffusional transformation.

This page discusses:

You must include a property table of type "ABQ_PHASE_TRANS_Diffusional_JMA_Coefficients" in the material definition to specify the coefficients of the Johnson-Mehl-Avrami (JMA) model for a diffusional transformation whose input option is set to JMA in the parameter table of type "ABQ_PHASE_TRANS_Transformations".

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