Preparation method of thin-wall tubular product of particle-reinforced aluminum-based composite material

Abstract

The invention relates to a preparation method of a thin-wall tubular product of a particle-reinforced aluminum-based composite material, which comprises the steps of: 1, preparing a tube blank by adopting a mixing and casting process and a powder metallurgy process; 2, homogenizing the tube blank, turning and stripping, carrying out a high-temperature compression deformation test to obtain a suitable processing deformation condition; 3, spinning the tube blank for finite element number value simulation, optimizing process parameters, and thermally spinning and warmly spinning; and 4, carrying out solution treatment on the obtained tubular product, and ageing after water hardening at room temperature. The tubular product prepared by the invention has larger diameter wall thickness ratio, smooth internal surface and outer surface without defects, uniform wall thickness and better interface combination between reinforced particles and a base body of the thin-wall tubular product. The method has short procedure, labor saving of the processing mode, energy saving and environmental protection, simple process, low raw material cost, suitability for large-scale production and better popularization value, and can be widely applied to the preparation of high-strength light tubular products in the fields of aerospace, vehicles, advanced weapons and the like.

Description

technical field

[0001] The invention relates to a method for preparing thin-walled pipes of particle-reinforced aluminum-based composite materials, which belongs to the field of preparation of thin-walled pipes of difficult-to-form materials. Background technique

[0002] Particle-reinforced aluminum matrix composites have the advantages of high specific strength, high specific modulus, good wear resistance and dimensional stability, and are widely used in aerospace, automobile manufacturing, advanced equipment and other fields. Particle-reinforced aluminum matrix composite pipe fittings are lightweight, high-strength, high-modulus components, which can further reduce the weight of aerospace equipment, and are urgently needed in advanced weapons. After searching the existing technical literature, it is found that Chinese patents have not yet publicly reported the preparation method of the particle-reinforced aluminum matrix composite thin-walled pipe.
