The mechanism of the anomalous behavior of the plastic flow of materials with high crystal relief caused by the dynamic impurity subsystem

A model of dynamic interaction dislocations with an impurity subsystem crystals a high potential relief the crystal lattice (Peierls barriers) is developed. Such materials include metals body-centered cubic structure, semiconductors, ceramics, and many others. It shown that modification migration barriers near dislocation core significantly affects segregation impurities on moving dislocation. The presence substantially nonequilibrium initial stage kinetics leading to anomalies dynamics yield strength substantiated. Keywords: dynamics, in core, synergetics subsystems, stable unstable regimes, plastic flow anomalies.
