TL;DR: In this paper, the mechanisms governing twin-induced strain hardening of high-purity α-titanium at room temperature were incorporated into constitutive laws to describe the evolution of both twin and slip resistance due to deformation twinning.

TL;DR: In this paper, the mechanical behavior of transformation-induced plasticity (TRIP)-assisted multiphase steels is addressed based on three different microstructures generated from the same steel grade.

Journal ArticleDOI
TL;DR: In this article, a high density of growth twins in pure Cu imparts high yield strength while preserving the capacity for efficient dislocation storage, leading to high strain hardening rates at high flow stresses, especially at 77 K.
Abstract: A high density of growth twins in pure Cu imparts high yield strength while preserving the capacity for efficient dislocation storage, leading to high strain hardening rates at high flow stresses, especially at 77 K. Uniform tensile deformation is stabilized to large plastic strains, resulting in an ultrahigh tensile strength of similar to1 GPa together with an elongation to failure of similar to30%.

Journal ArticleDOI
TL;DR: In this paper, the model for the plastic behavior of steels during phase transformations was extended to include strain-hardening effects (isotropic or kinematic hardening) and an expression for the transformation plastic strain rate was obtained by modifying the treatment of Part I in a suitable manner.

TL;DR: The plastic flow behavior of Hadfield manganese steel in uniaxial tension and compression is shown to be greatly influenced by transformation plasticity phenomena as mentioned in this paper, consistent with a softening effect of twinning as a deformation mechanism and a hardening effect on the twinned microstructure.
Abstract: The plastic flow behavior of Hadfield manganese steel in uniaxial tension and compression is shown to be greatly influenced by transformation plasticity phenomena. Changes in the stress-strain (σ−e) curves with temperature correlate with the observed extent of deformation twinning, consistent with a softening effect of twinning as a deformation mechanism and a hardening effect of the twinned microstructure. The combined effects give upward curvature to the σ−e curve over extensive ranges of plastic strain. A higher strain hardening in compression compared with tension appears to be consistent with the observed texture development. The composition dependence of stacking fault energy computed using a thermodynamic model suggests that the Hadfield composition is optimum for a maximum rate of deformation twinning. Comparisons of the Hadfield steel with a Co-33Ni alloy exhibiting similar twinning kinetics, and an Fe-21Ni-lC alloy deforming by slip indicate no unusual strain hardening at low strains where deformation is controlled by slip, but an unusual amount of structural hardening associated with the twin formation in the Hadfield steel. A possible mechanism of anomalous twin hardening is discussed in terms of modified twinning behavior (pseudotwinning) in nonrandom solid solutions.
