Plastic deformation mechanisms of biomedical Co–Cr–Mo alloy single crystals with hexagonal close-packed structure
(2018-01-01)
This is the first report of the successful fabrication of Co–Cr–Mo biomedical alloy single crystals with a hexagonal close-packed (hcp) structure and the resultant clarification of its deformation behavior. The (0001)〈112¯0〉 ...
Fluid-present deformation aids chemical modification of chromite: Insights from chromites from Golyamo Kamenyane, SE Bulgaria
(Elsevier, 2015)
Chemical signatures of chromitites are commonly used to track the evolution of the Earth's mantle. However, chemical modification during deformation may have important implications for the interpretation of chromites' ...
Deformation and magma transport in a crystallizing plutonic complex, Coastal Batholith, central Chile
(Geological Soc. Amer., 2015)
The Carboniferous-early Permian Santo Domingo complex in coastal Chile (33.5 degrees S) preserves magmatic structures that allowed us to partially reconstruct and compare the deformation histories of two intrusive units ...
Evolution of magnetic properties and crystallographic texture in electrical steel with large plastic deformation
(AMER INST PHYSICS, 2011)
Deformation leads to a hardening of steel due to an increase in the density of dislocations and a reduction in their mobility, giving rise to a state of elevated residual stresses in the crystal lattice. In the microstructure, ...
Plastic deformation in nanoindentation of tantalum: A new mechanism for prismatic loop formation
(Elsevier, 2014-08)
The mechanisms of deformation under a nanoindentation in tantalum, chosen as a model body-centered cubic (bcc) metal, are identified and quantified. Molecular dynamics (MD) simulations and indentation experiments are ...
Plastic deformation of a porous bcc metal containing nanometer sized voids
(Elsevier Science, 2014-06)
Nanoporous materials, can present an outstanding range of mechanical properties. Both molecular dynamics and dislocation analysis were used to evaluate and quantify the evolution of plasticity in a porous Ta single ...
Deformation and geochronology of syntectonic granitoids emplaced in the Major Gercino Shear Zone, southeastern South America
(ELSEVIER SCIENCE BV, 2010)
The Major Gercino Shear Zone is one of the NE-SW lineaments that separate the Neoproterozoic Dom Feliciano Belt, of Brazil and Uruguay, into two different domains: a northwestern supracrustal domain from a southeastern ...
Numerical study of the effect of martensite plasticity on the forming limits of a dual-phase steel sheet
(Springer France, 2016-09)
The formability prediction of dual-phase steel sheets is highly important in the present automotive industry. In this study, the forming-limit curve (FLC) of a DP-780 steel sheet is predicted based on the well-known Marciniak ...
Stress induced martensitic transformations and phases stability in Cu-Al-Be shape-memory single crystals
(Elsevier Science Sa, 2013-10)
The stress induced martensitic transformations between different metastable phases in Cu–Al–Be shapememory alloy single crystals were assessed experimentally. In particular, the successive stress induced transformations ...
Quartz recrystallization regimes, c-axis texture transitions and fluid inclusion reequilibration in a prograde greenschist to amphibolite facies mylonite zone (Ribeira Shear Zone, SE Brazil)
(ELSEVIER SCIENCE BV, 2010)
The crystal-plastic behavior of quartz mylonites from the Ribeira Shear Zone (SE Brazil), a major strike-slip structure that was active during a prograde metamorphic phase related to the Neoproterozoic Brasiliano-Pan African ...
