TL;DR: In situ neutron diffraction has been used to investigate the deformation twinning and untwinning during cyclic uniaxial straining of hydrostatically extruded AZ31 magnesium alloy.

TL;DR: In this article, the deformation twinning of two ZM20 Mg alloys with significantly different grain sizes at room temperature was studied and it was shown that yielding and immediate post-yielding plasticity in compression along the extrusion direction is governed primarily by twin nucleation, whereas plasticity at higher strains is presumably governed by twin growth and dislocation slip.

TL;DR: In situ neutron diffraction and Elasto-Plastic Self-Consistent (EPSC) polycrystal modeling have been employed to investigate which deformation mechanisms are involved in the plasticity of extruded AZ31 Mg alloy during the tensile loading along the extrusion direction as mentioned in this paper.

TL;DR: In this article, the deformation behavior of two transformation induced plasticity (TRIP)-assisted steels with slightly different microstructures due to different thermo-mechanically controlled processing (TMCP) was investigated by the in situ neutron diffraction technique during tensile straining at room temperature and two elevated (50 and 100°C) temperatures.

TL;DR: In this article, the authors used Neutron diffraction to follow in situ the stress-induced martensitic transformation during uniaxial tensile testing of polycrystalline Fe-25.
