The Flow Behavior of Ultrafine-Grained Materials

Advanced Materials Research, 2014
Processing through the application of severe plastic deformation (SPD) leads to very significant grain refinement with grains that are typically in the submicrometer or even the nanometer range. These ultrafine-grained (UFG) materials provide an opportunity for achieving exceptional flow properties including high strength at ambient temperature and, if

The significance of diffusional flow in ultrafine-grained materials

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1998
Plastic deformation of crystalline materials at elevated temperatures can occur by intragranular dislocation motion or grain boundary related processes of diffusion creep. At relatively low stresses, where intragranular dislocation activity is limited, diffusional creep is likely to be a dominant mode of deformation.

Diffusion in Ultrafine Grained Materials

Materials Science Forum, 2008
The paper provides an overview of recent results of the radiotracer investigations of short-circuit diffusion in ultra fine grained (UFG) materials produced by severe plastic deformation (SPD). Different material classes (copper of different purity levels and Cu alloys) are considered.

Submicrosecond strength of ultrafine-grained materials

Mechanics of Solids, 2010
We present the results of measuring the strength properties of metals and alloys with face-centered cubic lattice (copper, aluminum), body-centered cubic structure (Armco iron, tantalum), hexagonal close-packed structure (titanium and titanium alloy BT6) in the original coarse-grained and submicrocrystalline state under shock-wave loading.

Erosion of conventional and ultrafine-grained materials

Thin Solid Films, 1984
Abstract The erosion behavior was investigated of wear-resistant coatings of SiSiC and WWC applied to steel and graphite substrates using the controlled nucleation thermochemical deposition (CNTD) process, a refinement of the chemical vapor deposition (CVD) process.

Ultrafine Grained Material Produced by Machining

Materials and Manufacturing Processes, 2010
The evolution of microstructure of carbon steel subjected to large plastic strain machining was investigated. The microstructure generated in machined chips was ultrafine grains with an average size of 200 nm. A finite element model was established to study large plastic deformation in plain orthogonal cutting.

Further processing of ultrafine-grain materials

International Journal of Material Forming, 2010
Linear flow splitting enables the production of bifurcated profiles out of sheet metal. Included in the Collaborative Research Centre (SFB) 666 the new roll forming procedure uses obtuse angled splitting rolls and supporting rolls to increase the surface of the band edge. High hydrostatic stresses in the deformed zone lead to an elevated formability of
