TBs are highlighted in blue color, while the relative SF density is indicated by the orange color bar. i–p Schematic illustration of the nanostructural evolution in the CrCoNi MEA and Ni during cyclic loading. q The cyclic mechanical loading curve for our experiments, where four characteristic ...
23). This likely occurs via a similar mechanism discussed above for superlattice growth (Fig. 2c–h) but on a substrate rather than on an existing 2D superlattice, i.e. after a critical Td density is reached such that adjacent trimer configurations appear on the surface (red particles Fig....
We do Density Functional Theory based total-energy calculations of the L 1 2 phase in Co 3 X and Ni 3 X compounds, X being a transition metal element. The lattice parameters, magnetic moments and formation enthalpies are determined and compared with the available experimental data. The (111)...

Abstract Generalized planar fault energy (GPFE) curves are widely used to evaluate the deformation behavior of metals and alloys. In the present work, a systematic analysis of the microscopic plastic deformation mechanism of face-centered cubic Al in comparison to Cu was conducted based on GPFE ...

The study area shows a landscape of high-density and deep-cut gullies with a gully density of 3.8 km/km2 [50], and consequently an extremely broken and undulating topography. Three main gully types exist on the Chinese Loess Plateau: hillslope gully, valley floor gully and valley bank gully...
As stated in [16], the information density that is contained in the uncertainty matrix is too high for users who only want a single number. In addition, the uncertainty matrix cannot easily be used for the decision of either acceptance or rejection. Evaluations of measurement uncertainty should...
