Abstract

This paper presents the results of an experimental investigation of the behavior of an annealed low-carbon steel subjected to rapidly applied constant stresses less than the static upper yield stress. Sensitive measurements of plastic and anelastic microstrain were made and the relationship between stress and equilibrium microstrain determined. The experimentally observed microstrain is quantitatively explained by a dislocation-generating mechanism. The equilibrium number of dislocation loops produced by a Frank-Read source is estimated as a function of the applied stress and the dislocation source length. Comparison of the theory and the experimental data leads to the determination of a characteristic length of dislocation which agrees with previous concepts of a mosaic block structure.
