“…Here all the values of the hardening matrix (diagonal and off-diagonal values) are set to 1 such that all deformation systems are assumed to contribute equally to the hardening of each other (i.e., no latent hardening is accounted for). Beyerlein et al [27] also used the predominant twin reorientation scheme to assess the twin volume effect during the VPSC modelling of the rolling texture in Ag-Cu cast eutectic nano-composite.…”

. (2013). Microstructure and texture evolution in a twinning-induced-plasticity steel during uniaxial tension. Acta Materialia, 61 (7), 2671-2691.Microstructure and texture evolution in a twinning-induced-plasticity steel during uniaxial tension AbstractA combination of electron back-scattering diffraction and X-ray diffraction was used to track the evolution of the microstructure and texture of a fully recrystallized Fe-24 Mn-3 Al-2 Si-1 Ni-0.06 C twinning-inducedplasticity steel during interrupted uniaxial tensile testing. Texture measurements returned the characteristic double fibre texture for face-centred cubic materials, with a relatively stronger 〈1 1 1〉 and a weaker 〈1 0 0〉 partial fibre parallel to the tensile axis. The interaction with the stable 〈1 1 1〉 oriented grains results in preferential plastic flow in the unstable 〈1 1 0〉 oriented grains. Consequently, the grains oriented along the 〈1 1 0〉 and 〈1 0 0〉 fibres record the highest and lowest values of intragranular local misorientation, respectively. The viscoplastic self-consistent model was used to simulate the macroscopic stress-strain response as well as track the evolution of bulk crystallographic texture by detailing the contributions of perfect and/or partial slip, twinning and latent hardening. The simulations revealed the dominant role of perfect slip and the limited volume effect of twinning on the texture development. The effects of initial orientation and grain interaction on the overall orientation stability during uniaxial tension showed that while the 〈1 0 0〉 fibre remains stable and does not affect the unstable orientations along the 〈1 1 0〉 fibre, the orientations along the stable 〈1 1 1〉 fibre strongly affect the unstable 〈1 1 0〉 orientations. on the overall orientation stability during uniaxial tension showed that while the 100  fibre remains stable and does not affect the unstable orientations along the 110  fibre, the orientations along the stable 111  fibre strongly affect the unstable 110  orientations.

“…The process causes TB migration: one side of the twin lamella decreases by one atomic layer and another side increases by one atomic layer. In the case of deformation twins [17,35,36], above τ m is deformation twin growth stress or deformation twin reduction stress in nanograins. Asaro and Suresh in [7] proposed a deformation twin initiation criteria based on the generalized stacking fault energy curve and showed that deformation twins of Al, Cu and Ni are achievable in comparison with partials' glide without twinning.…”

This paper analyses slip transfer at the boundary of nanoscaled growth twins in face-centred cubic (f.c.c.) metals for strengthening mechanism. The required stress for slip transfer, i.e. inter-twin flow stress, is obtained in a simple expression in terms of stacking fault energy and/or twin boundary (TB) energy, constriction energy and activation volume. For nanotwinned Al, Cu and Ni, inter-twin flow stress versus twin thickness remarkably shows Hall-Petch relationship. The Hall-Petch slope is rationalized for various reactions of screw and non-screw dislocations at the TB. Additionally, strengthening at the boundary of nanoscaled deformation twins in f.c.c. metals is analysed by evaluating required twinning stress. At small nanograin size, the prediction of deformation twin growth stress shows inverse grain-size effect on twinning, in agreement with recent experimental finding.

“…fcc-fcc and fcc-bcc. [17,22,[27][28][29][30] Many technically relevant metals have a hexagonal close packed (hcp) structure and, to date, making bulk nano-hcp metals has been a challenge with SPD techniques. [19,20,23,31,32] In this work, we develop a method using ARB to produce nanolayered Zr-Nb composites with layer thicknesses h of ∼90 nm.…”

“…[54,55] Compared with other texture measurement techniques, NeD enables statistically relevant data without potential modifications due to surface preparation. Texture measurements also provide a robust indicator of the primary deformation mechanisms, such as when interface-driven plasticity, [28,56] grain boundarymediated processes, [57] deformation twinning, [58][59][60] and partial-mediated slip [61] prevail. Figure 3 shows examples of textures at the micron scale and nanoscale in the form of pole figures, a compact way to present texture, as well as the standard texture presentation for Zr (albeit not for Nb).…”
