EXTERNAL LOAD INFLUENCE ON THE INTERACTION OF DISLOCATIONS WITH POINT DEFECTS

Real crystals, containing dislocations and point defects, are considered in the paper aiming at the theoretical investigation of diffusion processes, flowing in the field of a dislocation nucleus in an external load field. Their influence on the modification of plastic properties of crystals is aslo investigated in the paper. During the investigation methods of statistical physics and thermodynamics have been used as well as methods of mathematical physics and numerical modelling. As a result the new physics model of the diffusion kinetics in the field of a dislocation nucleus has been developed. The system of equations, describing this model, has been composed and solved. Processes of the modification of crystal plastic properties and internal friction in an external load field have been described. New methods for the determination of parameters of a disclocation structure and dislocation-admixture interaction on the internal friction results have been developed. New methods for the separation of dynamic and hysteresis losses have been created. Methods of the crystal disordering have been suggestedAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
