A detailed model for hysteresis is presented for metal hydride systems based on the
requirement for dislocation production during both hydride formation and hydride
decomposition. A quantitative illustration of the model is presented using the regular
interstitial solution approximation. The relationship between the solvus hysteresis and
pressure hysteresis is given. The model predicts that calorimetrically measured enthalpies
for hydride formation and decomposition will not exhibit any differences arising from …
