in hydrogen. The dehydriding was carried out by vacuum annealing of the as-milled powders. The microstructure and morphology of both the as-milled and subsequently dehydrided powders were characterized by X... destabilized. However, this needs to be further studied. By hydrogen discharge measurement, the time needed to achieve complete dehydriding upon vacuum annealing at 300 ?C was found to be about 120......
