Abstract

The Einstein flux equation is used to predict the concentrations of hydrogen in solid solution when hydrides precipitate in Zircaloy during fast cooling followed by isothermal interludes (constant hold temperatures) observed with synchrotron X-ray diffraction. A thermodynamic description is presented that challenges the current notion that precipitation is limited by kinetics. It also reinforces the claim that the solvus is closer to the temperature where precipitation starts, not to the temperature where precipitates dissolve.
