Thermodynamics of the relaxation applied to the behaviour of a nickel based alloy

This study gives a non linear thermodynamic approach of stress relieving of continuous mediums applied to the behaviour of a nickel-base alloy at 850 degrees C and undergoing various load treatments. We are trying to introduc e a physical interpretation of the phenomenological coefficients on which t he simulation rests, and are comparing our results to the model with intern al variables developed by Delobelle.
