Summary: Carburization heat treatment modeling will be reviewed. The data base needs will be discussed in terms of availability and accuracy requirements. The impact of inaccurate diffusivities and surface mass transfer coefficients will be presented in terms of carbon profiles and case depths. The relationships among the process parameters and the property specifications will also be presented.
