															Abstract:  In recent years, aluminum-matrix materials have been widely used in industry due to their high specific strength and fracture toughness. At pre-sent, severe plastic deformation (SPD) is the most effective process for fine crystallization of metals. Equal channel angel pressing (ECAP) has attracted much attention due to its stable preparation of ultrafine or nanocrystalline aluminum matrix materials with good comprehensive pro-perties. In this paper, the research progress of the preparation of aluminum-matrix fine-grained materials by ECAP technology is reviewed. The influence of process parameters such as extrusion temperature, friction coefficient, extrusion speed, extrusion path and back pressure on ECAP process of aluminum-matrix materials is comprehensively discussed by using finite element simulation and experiment. Through the analysis of the latest ECAP technology achievements at home and abroad, the possible development direction of this technology is prospected.
