| Abstract: | The microstructural characteristics of the advanced dual phase structure of austenite and bainite obtained in a high carbon silicon-containing low alloy steel, isothermally transformed, have been investigated and compared with that of the conventional types of microstructures. The influence of the isothermal transformation temperatures on the microstructures and the mechanical properties of the steel has been examined. Therefore, the strengthening mechanism of the new dual phase steel with ultra-high strength has been revealed. |
