Grain-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...

Grain growth in a bulk nanocrystalline Co alloy during tensile plastic deformation

A bulk nanocrystalline Co–P alloy was subjected to tensile tests. Grain growth from approximately 12 nm in the as-deposited state to about 25 nm after the tensile test was observed. Grain growth was not observed when the deforming volume was increased, or when the specimen was annealed at 433 K or above prior to the tensile tests. 2006 Acta Materialia Inc.

Atomistic based continuum investigation of plastic deformation in nanocrystalline copper

A continuum model of nanocrystalline copper was developed based on results from independent atomistic calculations on 11 bicrystals containing high angle grain boundaries. The relationship between grain boundary structure and its mechanical response was investigated. Based on the atomistic calculations; a constitutive law for grain boundary interfaces was implemented within a finite element cal...

MechanicaHy driven alloying and grain size changes in nanocrystalline Fe-Cu powders

Highly supersaturated nanocrystalline Fe,Culcc-X alloys (lO<n<95) have been prepared by mechanical alloying of elemental crystalline powders. The development of the microstructure is investigated by x-ray diffraction, differential scanning calorimetry, and transmission electron microscopy. The results are compared with data for ball-milled elemental Fe and Cu powders, samples prepared by inert ...
