The hydrogenation leads to Nd4Mg80Ni8 decomposing into NdH2.61-MgH2-Mg2NiH0.3 nanocomposites, where the high density phase boundaries provide a great deal of hydrogen atoms diffusion channels and nucleation sites of hydrides, which greatly enhances the hydriding/dehydriding (H/D) properties. The ...
The com- position design optimization of Al-Zn-Mg-Cu alloys is an effective method to enhance their comprehensive properties [7–10]. Al-Zn-Mg-Cu alloys are a kind of age-strengthened aluminum alloy. As strengthening elements, Zn and Mg can greatly improve the mechan- ical properties of ...

The textural properties and the surface composition changed with the (Ni + Mg)/Al atomic ratio of the precursor double-layered hydroxides. The BET surface area (Table 2) of Ni2Al and Ni1Mg1Al were similar, ca. 210 m2·g−1, and it was 200 m2·g−1 for Ni2Mg1Al. The pore ...
