Signi assembles titanium plate, aluminum plate/foil and stainless steel plate to form a titanium-aluminum-stainless steel sandwich structure, and then puts it in a vacuum hot pressing equipment, and processes it under the conditions of 1～4Mpa and 550～650℃ under pressure of 0.5～2 Hours, and then, after cooling treatment, a titanium-aluminum-stainless steel titanium steel composite plate is obtained. The operation method of the invention is simple, and the implementation is convenient. The titanium/aluminum and aluminum/stainless steel interfaces are uniformly diffused to form a metallurgical combination to obtain a titanium aluminum stainless steel clad plate.



In the preparation process of titanium aluminum stainless steel clad plate, the heating temperature is too high, the titanium and stainless steel matrix structure is thick, and the performance decline is insufficient. The use of aluminum foil as the intermediate layer to achieve the formation of metallurgical titanium-aluminum-stainless steel  plate can be significantly reduced The purpose of heating temperature to improve the performance of the composite board.
The method is simple to operate and easy to implement, which can ensure that the titanium-aluminum-stainless steel composite process has uniform bonding and good diffusion on the titanium-aluminum interface and the aluminum-stainless steel interface. The existence of the middle aluminum plate effectively prevents the diffusion of iron into the titanium matrix, prevents the formation of iron-titanium intermetallic compounds, and improves the shear strength and tensile strength of the titanium aluminum stainless steel clad plate. The titanium steel manufactured by this method The composite board can fully meet the requirements of subsequent processing.
