Dislocation-based strength model for high energy density conditions
Damian C. Swift, Kazem Alidoost, Ryan Austin +5
We derive a continuum-level plasticity model for polycrystalline materials in the high energy density regime, based on a single dislocation density and single mobility mechanism, w…
Analytic binary alloy volume-concentration relations and the deviation from Zen`s law
A. Landa, J. E. Klepeis, R. E. Rudd +2
Alloys expand or contract as concentrations change, and the resulting relationship between atomic volume and alloy content is an important property of the solid. While a well-known…
Elastic constants and volume changes associated with two high-pressure rhombohedral phase transformations in vanadium
B. Lee, R. E. Rudd, J. E. Klepeis +1
We present results from ab initio calculations of the mechanical properties of the rhombohedral phase (beta) of vanadium metal reported in recent experiments, and other predicted h…
Chemical bonding, elasticity, and valence force field models: a case study for alpha-Pt_2Si and PtSi
J. E. Klepeis, O. Beckstein, O. Pankratov +1
We have carried out a detailed study of the chemical bonding for two room-temperature stable platinum silicide phases, tetragonal alpha-Pt_2Si and orthorhombic PtSi. An analysis of…
On the structure and stability of germanium nanoparticles
Laurent Pizzagalli, Giulia Galli, John E. Klepeis +1
In order to control and tailor the properties of nanodots, it is essential to separate the effects of quantum confinement from those due to the surface, and to gain insight into th…
First principles elastic constants and electronic structure of alpha-Pt_2Si and PtSi
O. Beckstein, J. E. Klepeis, G. L. W. Hart +1
We have carried out a first principles study of the elastic properties and electronic structure for two room-temperature stable Pt silicide phases, tetragonal alpha-Pt_2Si and orth…
