Plastic accommodation at homophase interfaces between nanotwinned and recrystallized grains in an austenitic duplex-microstructured steel
The plastic co-deformation behavior at the homophase interfaces between the hard nanotwinned grain inclusions and the soft recrystallized matrix grains in a duplex-microstructured AISI 316L austenitic stainless steel is examined through the analysis of long-range orientation gradients within the matrix grains by electron backscatter diffraction and transmission electron microcopy. Our analysis ...
متن کاملHot Nanoindentation of Nanocrystalline Ni-W Alloys
High temperature nanoindentation experiments are conducted to assess the activation enthalpy for deformation of nanocrystalline Ni-W alloys, for grain sizes between 3 and 80 nm. Thermal softening becomes less pronounced at finer grain sizes, and the activation enthalpy has an apparent inflection at a grain size near ~10-20 nm, in the vicinity the Hall-Petch breakdown. This inflection is related...

15 صفحه اولPlasticity of nanocrystalline alloys with chemical order: on the strength and ductility of nanocrystalline Ni–Fe
Plastic deformation and alloying of nanocrystalline Ni-Fe is studied by means of atomic scale computer simulations. By using a combination of Monte-Carlo and molecular dynamics methods we find that solutes have an ordering tendency even if grain sizes are in the nanometer regime, where the phase field of the ordered state is widened as compared to larger grain sizes. Tensile testing of disorder...
متن کاملGrain-size dependence of plastic deformation in nanocrystalline Fe
Plastic deformation of nanocrystalline Fe was investigated by nanoindentation. Samples, synthesized by mechanical attrition, consisted of powder particles with diameters greater than 30 mm. The average grain diameters within the particles of different samples ranged from 10 nm to 10 mm. To avoid potential artifacts, samples were prepared without use of heat treatment, and measurements were cond...
