Texture analysis in hexagonal materials
TL;DR: In this paper, a brief summary of the texture in hexagonal structural materials is carried out, mainly dealing with the deformation and recrystallization texture as well as the anisotropy of textured hexagonal materials.
Journal ArticleDOI
New discoveries in deformed metals
TL;DR: In this article, the authors have shown that the microstructural evolution follows a universal pattern of grain subdivision from the macroscale to the nanometer scale, and that the similarity between the behavior of materials undergoing different deformation patterns forms the basis for future research and development encompassing traditional as well as new materials and processes.

Texture evolution in equal-channel angular extrusion
TL;DR: In this paper, texture development in metals of fcc, bcc, and hcp crystal structure processed by a severe plastic deformation (SPD) technique called equal-channel angular extrusion (ECAE) or equal channel angular pressing (ECAP) is discussed.
Journal ArticleDOI
Multistage strain hardening through dislocation substructure and twinning in a high strength and ductile weight-reduced Fe–Mn–Al–C steel
TL;DR: In this article, the authors investigated the kinetics of the deformation structure evolution and its contribution to the strain hardening of a Fe 30.5Mn-2.1Al-1.2C (wt.%) steel during tensile deformation by means of transmission electron microscopy and electron channeling contrast imaging combined with electron backscatter diffraction.

Long-range internal stresses and asymmetric X-ray line-broadening in tensile-deformed [001]-orientated copper single crystals
TL;DR: In this article, the authors showed that the asymmetric line profiles are due to the superposition of two mutually displaced symmetrically broadened line profiles, which can be ascribed to the material located in the cell walls and the cell interiors of the dislocation cell structure, respectively.

Grain orientation dependence of microstructure in aluminium deformed in tension
Xiaoxu Huang,Niels Hansen +1 more
TL;DR: In this paper, the evolution of deformation microstructure in medium to high stacking fault energy fcc metals has been described in terms of a general framework of grain subdivision involving the formation of rotates volume elements for all deformation modes.

A simple and rapid method for determining orientations and misorientations of crystalline specimens in TEM
TL;DR: In this paper, a method for determining orientation and misorientations of a crystalline specimen has been developed using a double-tilt holder for a transmission electron microscope (TEM), after tilting the specimen to allow one of the low-index zone axes for one crystallite to be close to the beam direction, the orientation of any crystallite can be obtained by determining the relative position of the Kikuchi pattern on the screen.

Versetzungsstruktur und verfestigung von [100]-kupfereinkristallen
TL;DR: In this paper, a cell structure consisting of nearly dislocation free regions of varying sizes surrounded by walls of dislocation networks without preferred orientation is observed which is, in principle, the same in all stages of deformation.

The effect of dispersed phases upon dislocation distributions in plastically deformed copper crystals
F. J. Humphreys,J. W. Martin +1 more
TL;DR: The effect of dispersions of either cobalt or silica upon the dislocation distributions in deformed copper crystals has been investigated in this article, showing that the precipitates caused an increase in the yield stress and in the rate of hardening in stage I.
