Kinetics of periodic processes during plastic flow

This paper establishes the dependence of the velocity of the self-consisten t motion of the foci of inhomogeneous plastic deformation on the strain-har dening coefficient during the stretching of single-crystal gamma Fe. It is shown that the relationship between the velocity and the indicated quantity is inversely proportional at the linear-hardening stage. An interpretation of the observed regularities is proposed on the basis of the concept of th e autowave character of the plastic flow of solids and of self-organization in a deformed medium. The dispersion law of the plastic-deformation autowa ves is established. (C) 1999 American Institute of Physics. [S1063-7834(99) 01907-3].
