Defined methods and techniques of research and research samples made of steel . In particular, high-carbon steel containing 0.5-1.2 parts by weight . % Carbon samples for study of the thermodynamic and kinetic conditions of the phase of vanadium oxide and reallocation depending on the carbon content of the chemical methods and X-ray phase analysis , the samples for investigation microalloying influence on carbon offset evtektoidnoy boundaries and thermal and kinetic parameters and polymorphic phase transformations dilatometric , metallographic , dyurometricheskim assays samples to study the effect of microalloying on the formation of micro - and substructure high carbon steels in the initial ( hot- ) state and after heat treatment for formation of pearlite , bainite and martensite structure by submikrotopografii surface qualitative elemental analysis of the surface of high-temperature X-ray diffraction , the samples to determine the fatigue endurance scheme cantilever bending , tensile and compressive strength, wear resistance in abrasive and contact - fatigue wear. Nitride dispersion hardening at optimum austenitizing temperature by increasing the stability of the austenite transformations reduces by 20 ... 65оC temperature range n , B , M transforms high-carbon steels , which enables to reduce by 15 ... 25% of the cooling rate after austenitization products . This simplifies the process of tempering or normalizing technological products and reduces the likelihood of multiplication cold cracking when hardening Product Description popup.authors Бабаскін Юрій Захарович Довготелес Віталій Вікторович Золотар Ніна Яківна Короленко Валентина Петрівна Короленко Дмитро Миколайович Литвин Анатолій Тімофійович Радченко Зінаїда Миколаївна Степанова Тетяна Василівна Шипицин Петро Якович Шипицин Сергій Якович popup.nrat_date 2020-04-02 Close
