“…When h = 10 nm, it is worthy to note that attenuated and broad in γ-Ni (111) peaks can be detected at 2θ between 42 • and 46 • , showing a lower crystallinity. This implies that the formation of the amorphous phase is promoted [41], resulting from disordered atom arrangements induced by more interfaces with a lower h. detected at 2θ between 42° and 46°, showing a lower crystallinity. This implies that the formation of the amorphous phase is promoted [41], resulting from disordered atom arrangements induced by more interfaces with a lower h. The cross-sectional FE-SEM images at a high magnification of the as-sputtered Ni/Ni3Al-MoW multilayers are shown in Figure 4.…”

The cross-sectional FE-SEM images at a high magnification of the as-sputtered Ni/Ni3Al-MoW multilayers are shown in Figure 4. It can be seen that the sharp interfaces are presented between alternating layers within the sputtered Ni/Ni3Al-MoW multilayers for h = 160 nm and 40 nm, and the h is consistent with the designed value of the multilayers.…”

The mechanical properties of nanocrystalline pure Ni films are degraded due to grain coarsening with exposure for a long time in ambient. In order to further improve the mechanical properties of Ni-based thin films, as-sputtered Mo-W co-doped Ni/Ni3Al multilayered structures were constructed. When the individual layer thickness (h) is lower than 40 nm, both the average grain sizes and the crystallinity degrees are degraded, showing a tendency for the formation of the amorphous phase. With h = 40 nm, nano-twins were observed as (111) twining interfaces for the multilayers due to the reduction of the stacking fault energy by the co-doping of Mo-W, whereas the nucleation and growth of the nano-twins were limited, without observations for the Mo-W co-doped Ni/Ni3Al multilayer with h = 10 nm. The hardness of the multilayers was enhanced, and the elastic modulus was reduced at a lower h, owing to the grain refinements and layer interface barriers for strengthening, and the existence of the amorphous phase with the inferior modulus, respectively. The resistance against the fracture was enhanced due to toughening by the lamellar structure for the Mo-W doped Ni/Ni3Al multilayer at h ≤ 40 nm. Comprehensively, the Mo-W-doped Ni/Ni3Al multilayer with 10 nm displays a superior mechanical performance.
