metadata.name: dc.description.abstract
metadata.value: A brief review of the theoretical models which describe specific plastic deformation micromechanisms
  in nanotwinned materials is suggested. Novel nanotwinned materials (ultrafine-
  grained metallic materials with high-density ensembles of nanoscale twins within
  grains) exhibit simultaneously high strength and good ductility at room temperature.
  These characteristics of nanotwinned metals are very important for practical applications.
  However, micromechanisms responsible for the unique combination of high strength and
  ductility in nanotwinned metals have not yet been determined and represent the subject
  of intensive discussions. According to experimental data, the specific deformation mechanisms
  operate in nanotwinned materials. One of the specific deformation mechanisms in nanotwinned metals is widening of nanoscale twins due to stress-driven migration of twin
  boundaries. Another specific deformation mechanism in nanotwinned metals is detwinning
  process which was experimentally observed by several research groups in nanotwinned copper
  (Cu). In the framework of the models, micromechanism of nanotwin widening due to
  coherent twin boundary migration and detwinning micromechanism through migration of
  incoherent twin boundaries in nanotwinned materials are considered. Results of the theoretical
  models demonstrate good agreement with corresponding experimental data.
