Abstract
Винахід належить до здатної деформуватися сталі для виготовлення полегшених конструкцій з властивостями TRIP та TWIP, що містить елементи, мас. %: С - 0,05-1,0, Аl - до 11,0, Si - до 6,0, Al + Si > 0,05, Mn - 9,0-25,0, H < 20 ч./млн., решта - залізо та супутні для сталі елементи. Сталь характеризується тим, що низькому вмісту марганцю відповідає підвищений вміст вуглецю і підвищеному вмісту марганцю відповідає низький вміст вуглецю, при цьому парні значення С-Mn розташовуються у системі координат С-Мn приблизно на одній прямій сполучній лінії, віддаленій від сполучної лінії парних значень С-Mn, що знаходяться у рівноважному стані між аустенітною фазою γ та мартенситною фазою α'.$Изобретение относится к способной деформироваться стали для изготовления облегченных конструкций со свойствами TRIP и TWIP, содержащей элементы, мас. %: С - 0,05-1,0, Аl - до 11,0, Si - до 6,0, Al + Si> 0,05, Mn - 9,0-25,0, H <20 ч. / млн., остальное - железо и сопутствующие для стали элементы. Сталь характеризуется тем, что низкому содержанию марганца соответствует повышенное содержание углерода и повышенному содержанию марганца соответствует низкое содержание углерода, при этом четные значения С-Mn располагаются в системе координат С-Мn примерно на одной прямой соединительной линии, удаленной от соединительной линии четным значений С - Mn, которые находятся в равновесном состоянии между аустенитной фазой γ и мартенситной фазой α '.The invention relates to a deformable steel for the manufacture of lightweight structures with TRIP and TWIP properties, containing elements, wt. %: С - 0.05-1.0, Аl - up to 11.0, Si - up to 6.0, Al + Si > 0.05, Mn - 9.0-25.0, H < 20 ppm, the rest - iron and elements associated with steel. The steel is characterized by the fact that a low manganese content corresponds to an increased carbon content and a high manganese content corresponds to a low carbon content, while the even C-Mn values are located in the C-Mn coordinate system approximately on one straight connecting line, distant from the connecting line of the even C-Mn values, which are in an equilibrium state between the austenite phase γ and the martensite phase α'.$The invention relates to deformable steel for the production of lightweight structures with TRIP and TWIP properties, containing elements, wt. %: C - 0.05-1.0, Al - up to 11.0, Si - up to 6.0, Al + Si> 0.05, Mn - 9.0-25.0, H <20 parts per million, the rest - iron and elements associated with steel. Steel is characterized by the fact that a low manganese content corresponds to an increased carbon content, and an increased manganese content corresponds to a low carbon content, while the even C-Mn values are located in the C-Mn coordinate system approximately on one straight connecting line, distant from the connecting line by the even C - Mn values, which are in equilibrium between the austenite phase γ and the martensitic phase α'.
