Journal ArticleDOI
Sample-size effects in the yield behavior of nanocrystalline nickel
TL;DR: In the case of nanocrystalline nickel pillars, for which there is a fixed microstructural length scale set by the grain size, the smaller is still stronger.
Journal ArticleDOI
Statistics of weak grain boundaries for spall damage in polycrystalline copper
Leda Wayne,Kapil Krishnan,S. Digiacomo,Narayan Kovvali,Pedro Peralta,S. N. Luo,Scott R. Greenfield,Darrin D. Byler,Dennis L. Paisley,Kenneth J. McClellan,Aaron C. Koskelo,Robert M. Dickerson +11 more
TL;DR: In this article, the relationship between spall damage and local microstructure was investigated using polycrystalline copper samples via laser-driven plate impacts at low pressures Electron backscattering diffraction was used to relate the presence of porosity to microstructural features such as grain boundaries and triple points.
Journal ArticleDOI
Strain mapping in nanowires.
J. L. Taraci,Martin Hÿtch,T. Clement,Pedro Peralta,Martha R. McCartney,Jeffery Drucker,S. T. Picraux,S. T. Picraux +7 more
TL;DR: A method for obtaining detailed two-dimensional strain maps in nanowires and related nanoscale structures has been developed using a combination of lattice imaging by high-resolution transmission electron microscopy and geometric phase analysis of the resulting micrographs using Fourier transform routines.
Journal ArticleDOI
Grain Boundaries in Uranium Dioxide: Scanning Electron Microscopy Experiments and Atomistic Simulations
Pankaj Nerikar,Karin Rudman,Tapan Desai,Darrin D. Byler,Cetin Unal,Kenneth J. McClellan,Simon R. Phillpot,Susan B. Sinnott,Pedro Peralta,Blas P. Uberuaga,Christopher R. Stanek +10 more
TL;DR: In this article, the distribution and atomic structure of grain boundaries has been investigated in UO 2, and the experimental data indicated that ∼ 16% of the boundaries were CSL boundaries and the CSL distribution was dominated by low Σ boundaries; namely E9, E3, and Σ5.
Journal ArticleDOI
Lattice models of polycrystalline microstructures: A quantitative approach
TL;DR: In this paper, two procedures based on the same methodology are presented in the two-dimensional case to achieve the rigorous mapping of the geometrical and the elastic properties of a disordered polycrystalline microstructure into a spring lattice.
