), a high-magnification image reveals that the matrix was polycrystalline, with a grain size of approximately 50 nm. EDS-1 and EDS-2 suggest that the matrix contained ~36% Al, ~48% Fe (mole fraction) (Table 4......
. (1)), in crystalline materials for example metals, the yield stress, as a criterion for the strength of polycrystalline materials, increases dramatically by grain refinement [13] σy=σ0+kyd-1/2 ......
indicate that the samples possess a polycrystalline structure that is composed of randomly oriented fcc Pd and that one of the lattice fringe spacings is 0.224 nm, which is consistent with the distance......
investigations were performed based on the direct application of Hall-Petch relationship. It is deemed imperative to produce nanocrystalline (NC) materials from the coarse-grained polycrystalline......
) plane of hexagonal phase of ZnS. This result confirms formation of crystalline nanorods. The polycrystalline nature of the sample is validated by SAED pattern (Fig. 2(d)) presenting a set of rings......
