Article

The optimum parameters for the continuous annealing of cold-rolled dual-phase steel are determined by the method of orthogonal design to obtain an ultimate rupture strength exceeding 1000 MPa and an elongation exceeding 12%. The microstructure of the steel is studied with the help of optical and transmission electron microscopy.
