INVESTIGATION OF THE MICROSTRUCTURAL BANDING IN STEEL 4140
DOI: 10.17804/2410-9908.2017.3.042-052 The microstructural banding of the 4140 steel is studied. The dependence of the anisotropy index on the bar diameter and sampling location is established in accordance with GOST R 54570 (ASTM E 1268). A relationship between microstructural banding (i.e. anisotropy index) and toughness is shown to exist. A correlation between the kinetics of isothermal austenite transformation in the 4140 steel and the chemical inhomogeneity of the steel is discussed.
Keywords: 4140 steel, microstructural banding, anisotropy index, toughness, bainite transformation References:

ИССЛЕДОВАНИЕ СТРУКТУРНОЙ ПОЛОСЧАТОСТИ В КОНСТРУКЦИОННОЙ СТАЛИ 40ХН2МА
Проведено количественное определение степени структурной полосчатости в конструкционной легированной стали 40ХН2МА. Установлена зависимость индекса анизотропии, определенного согласно ГОСТ Р 54570 (ASTM E 1268), от диаметра проката и места отбора пробы. Показано, что существует зависимость между структурной полосчатостью и анизотропией ударной вязкости. Рассмотрена взаимосвязь между кинетикой изотермического превращения аустенита в стали 40ХН2МА и химической неоднородностью стали, являющейся причиной полосчатости микроструктуры.
