Description

technical field [0001] The invention specifically relates to an aluminum-based composite material multi-directional two-stage constrained deformation device and a method for using the same. Background technique [0002] Aluminum-based composites combine the advantages of both the aluminum alloy matrix and the reinforcement, and possess high specific strength, high specific stiffness, and excellent physical properties. The important position, especially in the field of aerospace, puts forward higher requirements for lightweight, so it also further improves the quality requirements for aluminum matrix composites. [0003] Extrusion deformation is usually the main way of secondary molding of aluminum matrix composite materials at present. Through extrusion process, aluminum matrix composite materials undergo strong plastic deformation, improve the density of composite materials, and finally obtain aluminum matrix composite materials with excellent performance. However, the ext...
