specific Embodiment approach 1

[0021] Specific Embodiment 1: In this embodiment, a high elastic modulus titanium-based composite material with controllable structural properties uses industrially pure titanium and diamond as raw materials, and introduces TiCp and diamond into the material as a reinforcing phase through powder metallurgy methods; The industrially pure titanium is titanium powder, and the diamond is diamond powder; the volume of the diamond powder accounts for 5-15% of the total volume of raw materials.

specific Embodiment approach 2

[0022] Embodiment 2: This embodiment differs from Embodiment 1 in that: the diameter of the diamond powder is 2-10 μm; the titanium powder is spherical titanium powder with a diameter of 90-150 μm. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0023] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the volume of the diamond powder accounts for 10% of the total volume of the raw material. Others are the same as in the first or second embodiment.

Abstract

The invention provides a structural-performance-controllable high-elasticity-modulus titanium-based composite material and a preparation method of the structural-performance-controllable high-elasticity-modulus titanium-based composite material and relates to the structural-performance-controllable high-elasticity-modulus titanium-based composite material and the preparation method of the structural-performance-controllable high-elasticity-modulus titanium-based composite material. The structural-performance-controllable high-elasticity-modulus titanium-based composite material and the preparation method of the structural-performance-controllable high-elasticity-modulus titanium-based composite material aim to solve the problems that it is difficult for the elastic modulus of a titanium alloy to exceed 120 GPa, it is difficult for the elastic modulus of the titanium-based composite material to exceed 170 GPa, and the formability and processability of ceramic such as TiC are poor are solved. According to the structural-performance-controllable high-elasticity-modulus titanium-based composite material and the preparation method, industrial pure titanium and diamond are taken as raw materials, and TiCp and diamond reinforced phases are introduced into the material in a target manner through a powder metallurgy method. The blank of the titanium material with the elastic modulus being higher than 170 GPa is filled, the shape of the net structure is achieved by changing the ball milling process, and the diamond reacting dose is controlled by changing the sintering process. The preparation method is used for preparing the high-elasticity-modulus titanium-based composite material.

Description

technical field [0001] The invention relates to a high-elastic-modulus titanium-based composite material with controllable structural properties and a preparation method thereof. Background technique [0002] Titanium and titanium alloys have significant advantages such as high specific strength and corrosion resistance, and their application fields are very wide and are still expanding, including conventional industries such as aerospace, ships, chemical metallurgy, biomedical materials and art, sports, Daily necessities and many other aspects. However, with the development of various technologies, people have higher and higher requirements on the performance of materials, and pure titanium and titanium alloys can no longer meet the use requirements. Therefore, continuous fiber reinforced titanium matrix composites (CRTMCs) and discontinuously reinforced titanium matrix composites (DRTMCs) have been prepared to further improve the specific stiffness and service temperature...
