Evidence for orbital ordering in LaCoO3 [PDF]
, 2003 We present powder and single crystal X-ray diffraction data as evidence for a monoclinic distortion in the low spin (S=0) and intermediate spin state (S=1) of LaCoO3.

Twinning in Zr-Based Metal-Organic Framework Crystals
Chemistry, 2020 Ab initio structure determination of new metal-organic framework (MOF) compounds is generally done by single crystal X-ray diffraction, but this technique can yield incorrect crystal structures if crystal twinning is overlooked.

, 2016 Contraction twinning in magnesium alloys leads to new grains that are misoriented from the parent grain by a rotation of 56 deg around the a-axis. The classical theory of deformation twinning does not precise the atomic displacements and does not explain

Deformation mechanisms in nanotwinned metal nanopillars [PDF]
, 2012 Nanotwinned metals are attractive in many applications because they simultaneously demonstrate high strength and high ductility, characteristics that are usually thought to be mutually exclusive.

Displacive model of deformation twinning in hexagonal close-packed metals. Case of the (90 deg, a) and (86 deg, a) extension twins in magnesium [PDF]
, 2016 A crystallographic displacive model is proposed for the extension twins in magnesium. It is based on a hard-sphere assumption previously used for martensitic transformations.

Twinning to slip transition in ultrathin BCC Fe nanowires
, 2018 We report twinning to slip transition with decreasing size and increasing temperature in ultrathin $$ BCC Fe nanowires. Molecular dynamics simulations have been performed on different nanowire size in the range 0.404-3.634 nm at temperatures ranging from

Stress-strain response and microstructural evolution of a FeMnCAl TWIP steel during tension-compression tests [PDF]
, 2016 © 2016. The stress-strain response of a Fe-17.5Mn-0.7C-2Al TWIP steel during cyclic loading has been investigated by means of tension-compression tests within the strain limits of ±2%, ±5% and ±10%. In addition, the microstructural evolution during the ±

Twin-induced plasticity of an ECAP-processed TWIP steel [PDF]
, 2017 The TWIP steels show high strain hardening rates with high ductility which results in high ultimate tensile strength. This makes their processing by equal channel angular pressing very difficult.
