Extensive efforts have been made to improve the H/D properties of magnesium-based alloys by adopting novel preparation techniques3,4 to reduce the particles sizes or/and adding catalytic components such as transition metals (Ni3, Nb5, Ti6) and rare earth elements (RE = La7, Ce8,...
The as-prepared amorphous alloy powders possess excellent morphological properties, indicated by a narrow particle size distribution laid in the range between 78–103 nm with a spherical-like morphology, as displayed in the image of field-emission scanning electron microscope (FE-SEM) displayed in...
3.2.1. Influence of the Tensile Direction on Mechanical Properties for the Particular ECAP Routes Generally, it can be concluded that the highest YS and the lowest ultimate elongation were observed in TD for all routes. In contrast, the lowest YS value was observed for ND. The uniform ...

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 ...
Although adding Nd reduces the average grain size, there was no significant positive effect on the tensile and compression properties (Figure 3a,b). The difference in the mechanical properties was very small, the values were within the range of the standard deviations. The average value of the ...
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 ...
