摘　　要：将淬火后的Q235钢进行多道次大压下量(累积压下量达94%)冷轧制备出超高强度内生复合板,采用透射电镜及X射线衍射仪研究了该内生复合板的显微形貌。结果表明,制备出的内生复合板抗拉强度高达2112MPa,显微组织呈现层片状特征。The in-situ composite plate with ultra-high strength was manufactured by severe multiple-pass cold-rolling（accumulated relative reduction of 94%） with quenched steel Q235.The microstructure and composition of the composite plate was observed by transmission electron microscope and X-ray diffraction.The results show that,the tensile strength of the composite plate reaches 2112 MPa,the microstructure of the composite plate presents laminar feature.
