| 摘要 |
The invention relates to a method for producing a semi-finished product, especially steel strip, having a dual-phase microstructure and a tensile strength between 500 and 1000 MPa. The invention is characterized in that in order to establish a microstructure made of hard components such as martensite, bainite, and carbide having low percentages of residual austenite in a ferritic matrix which is substantially free of interstitially dissolved elements (IF character), the elements interstitially dissolved in the ferritic matrix such as carbon and nitrogen are bound by carbide-, nitride-, or carbon nitride-forming alloying elements such as Al, Mo, Nb, Ti, and V.
