A Numerical Model of Nitriding of a Gadolinium Specimen and Its Further Destruction during Storage

详细

A numerical model of nitriding of an isotropic gadolinium specimen and its states during further storage under normal conditions (room temperature and atmospheric pressure) is developed. The model is implemented on the basis of the principles of thermoelasticity and mass transfer. The dynamics of distribution of nitrogen (N) and gadolinium nitride (GdN) in the specimen, which represents an additional phase formed during nitriding of the specimen, is considered. An algorithm of numerical solution of model equations is given.
