摘要：

We show that an enhancement of diffusive atomic motion during plastic deformation can be observed by rotating-frame nuclear-spin-relaxation measurements. Na-23 NMR experiments were carried out as a function of temperature on NaCl single crystals during deformation at constant strain rate. Evaluation of the data yields the strain-rate and temperature dependences of the concentration of the excess vacancies accountable for the enhanced atomic diffusion. The result is discussed in view of formation and annihilation of the excess vacancies during the deformation process.
