Description
Technical field
The invention belongs to layered metal composite material preparing technical field, be specifically related to a kind of layered metal composite material bull sleeve drawing composite preparation process.
Technical background
Layered metal composite material utilizes compound technology of preparing to make 2 kinds or the different metal of two or more physics, chemistry or mechanical property on interface, realize strong bonded and a kind of new material prepared.Although each layer metal of layered metal composite material maintains respective original characteristic, but the performances such as its physics, chemistry, mechanics are obviously better than single metal, there is the performances such as higher intensity, corrosion resistance and good conduction, heat conduction, magnetic conduction, of many uses in fields such as Aeronautics and Astronautics, oil, chemical industry, automobile, electric power, electronics, defence and military and daily lifes.Therefore, the preparation of layered metal composite material receives the most attention of countries in the world in recent years.
Traditional layered metal composite material preparation method mainly comprises Compound Extrusion method, rolling by crimping, sleeve drawing method, galvanoplastic, hot dipping method, continuous casting process, casting daraf(reciprocal of farad), core-filled and continuously casted method, Continuous Casting with Dual Crystallizer method etc.First three kind belongs to solid phase complex method, and its metal source is easy to control, and instrument and supplies is fairly simple, has become a kind of main flow production method of metal current laminar composite; Latter five kinds belong to liquid-solid complex method, have the advantages such as short route, high efficiency, energy-saving and cost-reducing, low cost, but the more difficult control of the interface quality of its composition metal, and need special equipment; Galvanoplastic belong to electrochemical method, because there is the problems such as environmental pollution, applying and being subject to certain restrictions.
Sleeve drawing method prepares the main hubbing of one of layered metal composite material at present, by utilizing the dissimilar metal rod base of metal pipe billet jacket corresponding size, make jacket composite blank, obtain through room temperature drawing the bimetallic stratiform composite wire of dead in line that interface is mechanical bond, inside and outside metal.Compare with rolling with extrusion, adopt hubbing to prepare layered metal composite material and there is the advantages such as technique is simple, equipment investment is little, easy and simple to handle, cost is low, but, due to traditional hubbing prepare layered metal composite material time, general passage deformation extent and pressure all less, and usually at room temperature carry out, therefore the layered metal composite material of preparation often needs to carry out follow-up long-time diffusion annealing process, to realize good interface cohesion, there is energy resource consumption large, the bond quality of compound interface is difficult to control, interface diffusion layer is thicker, interface easily generates intermetallic compound, the quality and performance of product is difficult to meet instructions for use, and preliminary work hardening rate difference is large between two kinds of metals, plastic deformation difficult coordination, two kinds of metals are difficult to deform in same pace, drawing is easily broken, the problems such as lumber recovery is low.
