Embodiment 1

[0038] (1) Put 14.14g of Ti-6Al-4V titanium alloy powder into a cemented carbide mold with an inner diameter of 20mm, and place it in a spark plasma sintering system for preform sintering. After sintering, clean the sintered with deionized water The material was dried naturally to obtain a block material with a height of 10mm and a diameter of 20mm.

[0039] The parameters of the preform sintering are: heating up to 600°C at a heating rate of 100°C / min for sintering, sintering pressure at 300MPa, heat preservation and pressure holding for 3 minutes, and after heat preservation and pressure holding, cool to 200°C with the furnace to take out the material.

[0040] The obtained block material was polished with 500-grit sandpaper until metallic luster appeared on the surface of the block material, the actual density was measured, and the density of the block material was calculated to be 95.4%.

[0041] (2) Put the block material with a height of 10mm and a diameter of 20mm into ...

Embodiment 2

[0047] (1) Put 22.10g of Ti-6Al-4V titanium alloy powder into a cemented carbide mold with an inner diameter of 25mm, and place it in a spark plasma sintering system for preform sintering. The material was dried naturally to obtain a block material with a height of 10mm and a diameter of 25mm.

[0048] The parameters of the preform sintering are: heating up to 650°C at a heating rate of 100°C / min for sintering, sintering pressure at 300MPa, heat preservation and pressure holding for 5 minutes, and after heat preservation and pressure holding, cool to 200°C with the furnace to take out the material.

[0049] The obtained block material was polished with 500-grit sandpaper until metallic luster appeared on the surface of the block material, its actual density was measured, and the density of the block material was calculated to be 96%.

Abstract

The invention relates to a method for preparing a titanium alloy material, belonging to the technical field of metal material preparation. The method is as follows: (1) Ti-6Al-4V titanium alloy powder is placed in an inner diameter of Φ y Among the cemented carbide molds, a spark plasma sintering system is used for preform sintering. After sintering, it is cleaned and dried to obtain a block material; (2) the block material is placed in an inner diameter of Φ c Among the dies, thermal compression deformation-in-situ pressure forging is carried out in a spark plasma sintering system to obtain a titanium alloy material; the Ti-6Al-4V titanium alloy is an α+β dual-phase titanium alloy. The method realizes the preparation of the titanium alloy material only through the spark plasma sintering system, the method is simple and the efficiency is high; and the strength and plasticity of the titanium alloy material prepared by the method can be improved simultaneously.

Description

technical field [0001] The invention relates to a method for preparing a titanium alloy material, belonging to the technical field of metal material preparation. Background technique [0002] After nearly 70 years of rapid development, titanium alloy materials have become one of the most important alloy materials in the 21st century. Typical titanium alloy materials include Ti-6Al-4V, Ti-1100, Ti-6.5Al-3.5Mo, Ti-Mo- Ni, etc., and Ti-6Al-4V, as the first practical titanium alloy material, is regarded as a titanium alloy material because of its low preparation cost, light weight, high specific strength, good biocompatibility and good corrosion resistance. The ace in the field, and has a wide range of applications in aerospace engineering, military and biomedical fields. [0003] With the third scientific and technological revolution, various industries put forward higher requirements for the service environment of materials, and the development of titanium alloy materials wit...
