Predicting the hydride rim by improving the solubility limits in the Hydride Nucleation-Growth-Dissolution (HNGD) model

•The HNGD model was found to be unable to predict the hydride rim thickness under temperature gradient.•Two hypotheses, targeting the supersolubility and solubility, were proposed to address this issue.•The modified HNGD model accurately predicts the thickness of the hydride rim in a sample submitte...
