Abstract

The invention relates to a method for preparing a TiC and TiB hybrid reinforced Ti-Al-Sn-Zr-Mo-Si-based composite board, and relates to a method for preparing a titanium-based composite board. By the method, the problem that the tensile property of the conventional TiC granule reinforced Ti-Al-Sn-Zr-Mo-Si-based composite board is reduced drastically at the temperature of more than 650 DEG C. The method comprises the following steps of: calculating required titanium power, titanium diboride, graphite powder and other materials according to the volume percentage of TiC, TiB and Ti-Al-Sn-Zr-Mo-Si-based titanium alloys in the composite board; preparing a precast block by using the titanium power, the titanium diboride and the graphite powder, smelting the precast block together with other materials, and thus obtaining a cast ingot; and forging, rolling, performing heat treatment, and thus obtaining the composite board, wherein the tensile strength of the composite board is between 810 and 890MPa at the temperature of 650 DEG C, so the composite board can be used in the field of aerospace.

Description

technical field [0001] The invention relates to a method for preparing reinforced Ti-Al-Sn-Zr-Mo-Si matrix composite material plate. Background technique [0002] With the rapid development of aerospace technology and the automobile industry, the flight distance and flight speed of various new aircraft have increased, and higher and higher requirements have been put forward for lightweight, high-strength, heat-resistant materials and their precision thermoforming technology. Due to the many outstanding advantages of particle-reinforced titanium-based composites, such as: low density, high specific strength and specific elastic modulus, it can still maintain high enough strength and stiffness at high temperatures, etc., which makes it suitable for aerospace, aviation and Very competitive material for heat-resistant structural profiles for automotive applications. At present, major developed countries in the world are actively carrying out research work on particle-reinforced...
