Transition from interfacial to diffusional growth during hydrogenation of Mg

The transition from interfacial to diffusional growth during hydrogenation of Mg arrow right MgH2 (hydride) at 210 degree C for 300min is studied using Johnson-Mehl-Avrami-Kolmogorov equation The growth dimensionality (n) decreases from 0.73 to 0.23. 1D (hydride/metal) interfacial growth occurs when...
