Flat product, such as sheet, made of steel having a high yield strength and exhibiting good ductility and process for manufacturing this product |
摘要 |
A flat product made of multiphase steel and a method for preparing the steel includes hot rolling at a temperature at which the austenite phase is stable, then tempering to form a C and Mn-enriched phase in a matrix, followed by a heat treatment to form austenite islands and/or enriching in Mn the already formed austenite and cooling down to room temperature so as to obtain a final product with a ferrite matrix containing residual austenite, bainite and/or martensite islands.
