摘要： The invention relates to a new preparation technique of composites, in details, i.e. a method of producing laminated composite materials of different alloys. In the preparation method, the bi-layer or multi-layer composites are prepared by means of the equal channel angular extrusion/pressure (ECAE/ECAP). Firstly, the appropriate alloys pairs or groups are selected, and the rational arrangements are carried out after pre-treating surfaces; then, the clad process is performed by extrusion and shear deformation in ECAE die; finally, the composite material is produced after one single pass or multiple passes clad extrusion. The annealing treatment can be performed subsequently to enhance the interfacial bonding strength by diffusion after the clad extrusion, and the heat treatment parameters consist of annealing temperature and holding time, which are chosen carefully to meet the demands of the refining microstructures and good properties for both the interfaces and individual component metals. Consequently, the layer-metal composite is produced with the firmly bonding interface, good microstructures and excellent properties. In the invention, the selection and assembling manners of the materials are very free, such as composites with bi-layer or interval multi-layer manners, and the method is suitable for most of the metal materials. The invention is a new method of fabricating composites and the preparation cost is low enough to meet the demand of large-scale industrial production.
