This work generalizes the one-step model previously developed on fcc-bcc martensitic transformations to the larger family of phase transitions in the fcc-bcc-hcp system. The angular distortive matrices are calculated for the bcc-fcc, bcc-hcp and fcc-hcp tr ...

Body-centered cubic metals are of high technological interest: for example tungsten as potential plasma facing component in future fusion reactors, molybdenum employed in aircraft parts, niobium as superconducting magnets, etc. The characteristics of their ...
A calculation method for accurately computing the displacement, image stress, and image energy induced by defects, such as cavities, precipitates, finite dislocation segments, and dislocation loops, in a free-standing anisotropic thin crystal film is prese ...
The activity and selectivity of structure-sensitive reactions are strongly correlated with the shape and size of the nanocrystals present in a catalyst. This correlation can be exploited for rational catalyst design, especially if each type of surface atom ...

The combined influence of prior plastic strain in austenite and applied stress in the course of the transformation on the crystallographic texture of bainitic steel was studied. The experimental data were obtained using electron back scatter diffraction an ...
A detailed structural analysis of the surface supported self-assembly of terphenyl-4,4′′-dicarbonitrile molecules (NC−Ph3−CN) linked by Co adatoms on Ag(111) reveals different surface patterns depending on the constraints applied to the system. Without con ...
We present a multifrequency electron spin resonance study in the range of 4-420 GHz of the quasi-one-dimensional, nondimerized, quarter-filled Mott insulators, delta-(EDT-TTF-CONMe2)(2)X (X=AsF6, Br). In the high-temperature orthorhombic phase above T simi ...
We investigate the dependence of band dispersion of the quantum spin Hall effect (QSHE) edge states in the Kane-Mele model on crystallographic orientation of the edges. Band structures of the one-dimensional honeycomb lattice ribbons show the presence of t ...

This work investigates the dislocation nucleation processes that occur at the tip of a crack in aluminum under a broad range of crystallographic orientations and temperatures. A concurrent multiscale molecular dynamics - continuum simulation framework is e ...
In the selective laser melting process, the scanning strategies have a deep impact on the final microstructures. In this paper, we point out the benefits of using EBSD techniques to characterize the scanning strategies on 18-carat gold samples. For a given ...
