| dc.description.abstractEn | This work proposes a new modeling of hydrolysis reaction in simulated seawater solution (35 g/L NaCl) with alloys containing α-Mg and Long Period Stacking Ordered (LPSO) phases. Alloys with different chemical compositions or thermal treatments were synthesized, leading to different (i) microstructures, (ii) α-Mg over LPSO phase fractions or (iii) LPSO type (18R or 14H). Classical nucleation and growth equation is used as an indicator of the reaction mechanisms but a new model is proposed to describe the complex kinetics curves (Vol (H2) = f(t)) obtained. This new model has several advantages: (i) it allows to discriminate the contribution of each phase, (ii) it could be applied to any alloy with phases reacting and (iii) it applies to the whole kinetics curves (i.e. from 0 to 100% yield). It is supported by the comparisons between the different alloys and SEM observations of their microstructure before and after exposure to the seawater solution. | |
