Single crystal studies have exposed that twining plays a significant role in dynamic recrystallization, yet in polycrystalline materials twining can play an important role in the propagation of dynamic recrystallization, mainly in low
stacking fault energy alloys.
This higher tensile stress was mainly caused by solid-solution hardening and a lower
stacking fault energy (SFE).
In the initial stage of fatigue damage (crack initiation stage), micromechanical properties of materials can vary with respect to vacancy, dislocation, twin,
stacking fault, and grain structure.
However, some theoretical studies have also suggested contradictive results as the (100) or (110) slip planes (18) and (010) (19) for PPv, primarily because these examined only particular structure modifications or calculated the generalized
stacking fault (GSF) energies of limited slip planes.
Among his topics are processing methods for nanomaterials, defect structure in low
stacking fault energy nanomaterials, correlation between defect structure and mechanical properties of nanocrystalline materials, the thermal stability of defect structures, and relationships between microstructure and hydrogen storage properties in nanomaterials.
The experimental investigations and thermodynamic analysis of the process of crystal growth from the vapour phase shows that the substrate temperature and the
stacking fault energy on the close-packed planes {111} have a strong effect on the density of the twinned boundaries (7).
The authors assume that the reason of worsening of the temperature of cold brittleness of chromium in case of its alloying by metals of the VII group, in particular manganese, is a not completely clarified character of change of a number of physical characteristics like dislocation structure, energy of
stacking fault, solubility of interstitial elements, degree of twinning deformation development, etc.
