Abstract:
Models of dislocation kink migration in disordered solid solutions and alloys are analyzed. Mechanisms of interaction of kinks with impurity subsystem leading to the hardening of crystalline materials are studied. Various approaches to the description of statistical patterns of kinks overcoming random potential reliefs are critically discussed. Conceptual features of the movement of kinks in impurity materials, leading to disagreements in interpretations of the phenomenon are noted. Qualitative picture of the anomalous kinetics of kinks in disordered media is described.
Keywords:dislocation kinks, solid solution hardening, random processes, anomalous kinetics.
