Titanium laminated metal composite material processing methods show diversification, of which the conventional composite methods include explosion welding composite method, explosion welding + rolling composite method, rolling method, extrusion composite method, surfacing method and brazing method. In view of the unique nature of titanium, the industry prefers to use explosion welding composite method, explosion welding + rolling composite method and extrusion composite method.
The first two methods, i.e. explosion welding composite method and explosion welding + rolling composite method, are mainly used for the production of composite plates. Explosion welding composite method is usually carried out at room temperature, through the energy generated by the explosion of titanium and other metals to achieve metallurgical bonding. While the explosion welding + rolling composite method is based on the explosion composite, the composite material is heated and rolled to further improve its bonding strength and performance.
Extrusion composite law is mainly used for the production of composite bar, composite pipe. The method through the preparation of the composite material and base material assembly or cast into solid or hollow ingot billet, and then extrusion, so as to obtain the desired shape of the composite material.
All three methods achieve metallurgical bonding of titanium with other metals, ensuring the strength and stability of the composite material.
In the past few decades, titanium composite material explosion welding technology has made rapid development. From scratch, with the continuous improvement of the level of technology and equipment, the product range has become increasingly rich, and the product structure has become more diversified. Today, not only can produce titanium-steel composite materials, but also successfully realized a series of layered titanium and titanium alloy composites such as titanium-copper, titanium-nickel, titanium-zirconium and so on.
Meanwhile, the production capacity has also been significantly improved with the continuous advancement of technology. Now we can not only produce double-layer and multi-layer metal composite plates, but also metal composite rods, pipes, etc., which further meets the demand for titanium laminated metal composites in different fields.
At present, in the production of laminated titanium and titanium alloy composite materials, the widely used titanium and titanium alloy grades include TA1, TA2, TA9, TA10, Gr1, Gr2, Gr12 and so on, which are highly favored because of their excellent performance and wide range of applications.
