Abstract

The invention discloses a method for preparing a hybrid aluminum-based composite material pipe, which includes loading particle-reinforced aluminum-based composite materials with different volume fractions into an aluminum alloy tube billet for pre-compacting, vacuuming, heating, perforating and hot extrusion compounding, Heat treatment (including annealing, quenching and aging) and other processes rely on high temperature and high pressure during extrusion to densify the particle-reinforced aluminum matrix composite material, and at the same time improve the composite strength of the interface between the particle-reinforced aluminum matrix composite material and the outer aluminum alloy matrix, and Improve the deformation ability of particle reinforced aluminum matrix composites, and solve the problems of poor plasticity and toughness of single particle reinforced aluminum matrix composites and difficulties in extrusion and manufacturing of hybrid aluminum matrix composites.

Description

technical field [0001] The invention belongs to the technical field of plastic processing of metal-based composite materials, and in particular relates to a preparation method of a hybrid aluminum-based composite material pipe. Background technique [0002] Particle-reinforced aluminum matrix composites have many excellent properties such as small specific gravity, high specific strength, elastic modulus, excellent high temperature performance, corrosion resistance, high wear resistance, etc., but their fracture toughness and plastic processing performance are better than aluminum alloy matrix. The material is poor. [0003] Metal layered composite material refers to a material with excellent comprehensive properties that is made of two or more layers of metals with different properties through a certain composite method. With the development of modern industrial technology and various new technologies and new industries, people's requirements for material performance are i...
