Abstract

The invention provides a preparation method of a high-temperature alloy semi-closed adapter pipe of a dual-layer thin-walled structure. The preparation method comprises the steps of design of a forming mold, design of a blank, forming of an outer pipe, filling of a core mold, assembly of an inner pipe, forming of the inner pipe, cutting away of the process end, heating core mold removal and the like. According to the preparation method, hydraulic forming is adopted, the forming manner is simple, the requirement for mold materials is low, the forming efficiency and forming precision are high, and cost is low; and a low-melting-point alloy is adopted as a semi-closed core mold free of a mold drawing clearance, semi-closed clearance forming is achieved, the core mold is easy to process and convenient to remove, and no residue is generated. The high-temperature alloy adapter pipe prepared through the method adopts the dual-layer structure, is high in rigidity and light and can serve as a high and low temperature conversion component.

Description

technical field [0001] The invention belongs to the technical field of superalloy forming and processing, and in particular relates to a method for preparing a superalloy semi-closed double-layer thin-walled transition tube. Background technique [0002] The need for supersonic flight and enhanced penetration capabilities. As a typical representative of the new generation of "killer" weapons, the supersonic cruise missile has a flight speed of Ma3.0 to 4.5, and a flight time of about 30 minutes. It is one of the key technologies for the development of supersonic cruise missiles. In the future, the hypersonic cruise missile Ma≥6, the surface temperature of the projectile body is ≥1100℃, and the severe aerodynamic heating environment puts forward new requirements for the structure material of the projectile body. New metal materials put forward higher requirements such as high strength, good plasticity, and high temperature resistance. When the engine is working normally, t...
