Modeling hydrolysis kinetics of dual phase α-Mg/LPSO alloys

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 different chemical compositions or thermal treatments were synthesized, leading to (i) microstructures, (ii) over LPSO phase fractions (iii) type (18R 14H). Classical nucleation growth equation is used as an indicator the mechanisms but model proposed describe complex kinetics curves (Vol (H2) = f(t)) obtained. has several advantages: it allows discriminate contribution each phase, could be applied any alloy phases reacting applies whole (i.e. from 0 100% yield). It supported by comparisons between SEM observations their microstructure before after exposure solution.
