It is shown that after isothermal quenching at 330 °С the bainitic reaction is accompanied by formation of austenitic phase with a size of 25-40 nm in cross-section stabilized by carbon and alloying additions. It is found that a phase transformation occurs under plastic deformation of bainitic cast iron quenched isothermically at 350 °С. A fifth of remained austenite transforms into martensite. This effect is responsible on increase in two times of wear resistance of cast iron, isothermically quenched according to above mentioned regime.5481 Product Description popup.authors Іванова Ольга Михайлівна Борисовська Катерина Михайлівна Бурдін Володимир Вікторович Вербило Дмитро Григорович Волощенко Сергій Михайлович Горна Ірина Дмитріна Даниленко Віталій Іванович Даниленко Микола Іванович Евич Ян Іванович Мінаков Микола Веніамінович Марченко Наталія Михайлівна Ремез Марина Віталіївна Тимошенко Ярослав Григорович Шуригін Борис Вікторович popup.nrat_date 2020-04-02 Close
