Estimation on stress of oxide layer in zirconium alloys

It has been reported that the effect of thermal redistribution of hydrides across the metal-oxide interface, coupled with thermal feedback on the metaloxide interface, is a dominating factor in the accelerated oxidation in zirconium alloys cladding PWR fuel. Basically this influence determines characteristic of oxide layer. Influence estimation for corrosion oxide layer due to hydrogen / hydride carried out because of investigation on the kinetic on accelerated oxidation due to hydride precipitation was preceded. Experimental result corroborative of concentration of stress at metal-oxide interface through bend test and XRD analysis was confirmed. Mechanical properties due to stress of oxide layer through nano-indentation and morphology was confirmed
