Kozik E.S., Svidenko E.V. INFLUENCE OF THERMAL PROCESSING USING VYSOKOENERGETICHESKIKH SOURCES ON THE OPERATIONAL PROPERTIES OF SOLID ALLOY T15K6The aim of this work is to study the effect of heat treatment using high-energy sources of heat (laser) on the operational properties of carbide inserts brand T15K6. As object of research used solid rods of alloy T15K6, size 5 х 5 х 35 mm. Was held microanalysis, in order to detect defects laser treatment processing, such as cracks, delaminations, conducted on e-Mickroscope Jeol ISM-6000 NeoScope with increasing ×1300. Determining the microhardness of the surface and near-surface layer before and after shot peening was performed using a microhardness tester PMT-3, while the load 1,96 N. Determination of the phase composition was performed using microdirect-meter MD-10. Using reginaspektor analysis determined the parameters of the PE array, the block size of the crystal lattice (D), microstresses (Δd/d). Under specified conditions, heat strengthening determined an approximate speed of travel of the beam of laser radiation relative to the part or de-hoist relative to the beam, which is then corrected. Justification Regis-Dom processing produced according to the planning matrix fractional replica from the provisions of the factors of experiment 24-1.Key words: heat treatment, laser processing, hard-alloy plates, microhardness.
