OPERATED FORMATION OF MECHANICAL PROPERTIES IN PRODUCTS METHODS OF COMPLEX LOCAL DEFORMATION
Process of complex local deformation, on an example of processing of the plug from a bronze alloy is considered. Mechanical properties of an investigated cast alloy are thus defined and parameters of distribution of microhardness on section of the processed preparation are investigated. Advantages of an offered method of formation of structure of metal are described. Schedules of dependence of distribution of various parameters of microhardness on section depending on number of operation cycles are constructed. The mathematical model of considered process in its comparison with experimental data is shown. Approximating dependences for distribution of parameters of microhardness are offered. Adequacy of mathematical model of process of complex local deformation is confirmed. As a result of mathematical modeling distribution on section of Odqvist parameter depending on number of passes is received. On the basis of the analysis of Odqvist parameter the scheme of operated formation of demanded mechanical properties in products is offered. That allows to set in advance necessary distribution of mechanical properties depending on processing parameters, in particular from number of operation cycles.
