Cyclic deformation leads to defect healing and
Nov 03 2015 · Producing strong and defect-free materials is an important objective in developing many new materials. Thermal treatments aimed at defect elimination often lead to undesirable levels of strength and other properties. Although monotonic loading can reduce or even eliminate dislocations in submicroscale single crystals such "mechanical healing" causes severe plastic deformation and Nov 03 2020 · Neuropathic pain caused by a lesion or disease of the somatosensory nervous system is a common chronic pain condition with major impact on quality of life.
