Description |
The transition from interfacial to diffusional growth during hydrogenation of Mg -> MgH2 (hydride) at 210 degrees C for 300 min is studied using Johnson-Mehl-Avrami-Kolmogorov equation (alpha = 1 - exp(- kt(n))). The growth dimensionality (n) decreases from 0.73 to 0.23. 1D (hydride/metal) interfacial growth occurs when n > 0.50, suggested by constant interface velocity (U). Diffusional growth at n
