Description
Technical field
The present invention relates to the Composite Preparation technology, specifically a kind of Ti-TiAl
3The preparation method of metal/intermetallic compound laminar composite.
Background technology
Along with the appearance of the development of modern industrial technology and various new technology, new industry, people increase day by day to the requirement of material property, and the performance of single group element material has been difficult to meet the demands under some working condition.Therefore, research has become important developing direction in the Materials Science and Engineering field with the preparation advanced composite material (ACM).Layer metal composite plate is to be composited by special preparation for processing by two kinds of different metallic plates of performance, compare with single metal constituent element, combine two kinds of metal constituent elements advantage separately through the laminated composite plate after the appropriate design combination, can obtain physics and chemical property that single metal does not have.In recent decades, the development of layer metal composite plate, production and application more and more cause people's attention, the new material that has become countries in the world competitively to develop.Up to the present, this composite has obtained application in fields such as Aero-Space, oil, chemical industry, metallurgy, machinery, automobile, steamer, building, nuclear energy and electric power and electronics.The manufacturing process of laminated-metal composite mainly contains following two kinds of methods:
1. explosive welding composite algorithm.The metallic explosive welding is to drive compound plate high velocity impact substrate by the high-strength chemical energy that explosive charge produces, the instantaneous pressure that the point of impingement produces has not only destroyed the oxide film on metallic plate top layer, exposed fresh surface, and formed skim on the fresh metal surface and have the welding transition district of plastic deformation, fusing, diffusion and wave character exposing, thereby realize the new technology and the new technology of a kind of metal solder of strong combination.Different with the substrate installation form according to compound plate, explosive welding can be divided into parallel method and preset angle configuration.When parallel method was installed, it is parallel that compound plate and substrate are in, and the gap remains unchanged; The angle rule is angled installation between compound plate and the substrate.The difference of explosive welding composite algorithm and other method is: (1) high pressure; (2) high strain rate; (3) locality of used load and mobility; (4) the composite plate compound interface presents wavy combination; (5) restriction that not differed greatly by material melting point, plasticity, and compound dimensions flexibility is very big.
2, roll-bonding method.The basic principle of roll-bonding method is meant that metallic plate is being subjected under the effect that milling train is applied thereto crunch, double layer of metal treat composite surface generation plastic deformation, surface metal-layer is broken.Subsequently, clean and metal level activation exposes from the metal surface of breaking, under the crunch effect, form plane metallurgical binding.Faying face continues to enlarge in follow-up heat treatment process, forms firm combination.Rolling fundamental difference compound and that the monometallic plate is rolling is, must impose big initial reduction in pass, impels the physics contact of composite surface.
Summary of the invention
The present invention designs the laminar composite that preparation is formed by connecting by ductile metal and hard crisp intermetallic compound alternative stacked, and utilizes the effect of reaction diffusion to reach the good interface combination.Occur in the cold-rolled process in order to solve: the Ti/Al interface is in conjunction with the problem of the composite board delamination splitting that occurs in bad and subsequently the vacuum heat process.It is compound to the present invention proposes new combination process-accumulation hot rolling, and this new method has excellent mechanical property, for example high strength and high tenacity with respect to traditional coarse grained metal material.Accumulation ply rolling method has practical significance, and it just can be realized by the common operation of rolling.
