Investigation on the Plastic Strain Dependence of Dislocation Velocity Using Dislocation Velocity-Stress Exponent and Dislocation Velocity Coefficient

To investigate the plastic strain dependence of dislocation velocity, stress relaxation tests with various plastic strains were performed using 590-MPa grade ferrite-bainite steel at room temperature. The amount of the stress drop at both 1.00 s and 6.00 × 101 s after the beginning of strain holding...
