摘要 The microstructure characteristies of the dual phase strueture of austenite and bamite obtained in a silicon high carbon low-alloy steel,isothermally transformed, have been inverstigated and compared witb that of the conventionai types of mierostructure. The influence of the isothermal transformation temperatures on the mierostrueture and the mechanical properties of the steel bas been examined. Therefore, the strengthening meehanism of the new dual phase steel with ultra-high strength has been revealed.
