Determination of Dislocation Velocities and Densities from the Deformation Waves of Discontinuous Yielding,
Abstract
The deformation waves that accompany the repeated discontinuous yielding of metals are analyzed with respect to utilizing their characteristics to determine dislocation velocities and densities as functions of stress and strain. Repeated yielding experiments were performed on annealed 2024 aluminum alloy and an alpha brass using a 'dead weight' loading apparatus. Measurements were taken of deformation wave velocities and widths and the associated plastic strain increments and strain rates. The calculated dislocation velocities and densities appear to be reasonable and consistent. (Author)
