Summary

IN THE FRAMEWORK OF THE MECHANISM OF THERMAL INSTABILITY THE EFFECT OF SUPERCONDUCTING TRANSITION ON THE STABILITY OF LOW TEMPERATURE PLASTIC DEFORMATION OF METALS IS ANALYSED. THE EXPERIMENTALLY OBSERVED AMBIGUOUS INFLUENCE OF SUPERCONDUCTING STATE ON THE LOW TEMPERATURE SERRATED FLOW IS BROUGHT ABOUT BY A NUMBER OF FACTORS, IN PARTICULAR, THAT UNDER S-STATE ALONGSIDE WITH MATERIAL THERMAL CHARACTERISTICS THE CHANGE MIGHT OCCUR IN THE TEMPERATURE DEPENDENCE OF FLOW STRESSES. COMPARISON OF THEORETICAL DATA WITH EXPERIMENT (ALUMINIUM, NIOBIUM, LEAD) MAKES IT POSSIBLE TO CONCLUDE THAT THE THERMAL MECHANISM GIVES A QUANTITATIVELY CORRECT PREDICTION OF THE TEMPERATURE-STRAIN RATE CONDITIONS FOR THE SERRATED DEFORMATION IN N-AND S-STATES OF THESE METALS.
