Embodiment 1

[0029] Please refer to figure 1 , Ti 50 Al 45 B 5 The powder includes 6.43 kg of titanium powder, 3.42 kg of aluminum powder, and 0.15 kg of boron powder. The obtained powder particles are all spherical in shape, with a particle size of 30-50 μm and an oxygen content of 0.09-0.14%. Put the obtained powder into a powder mixer and mix for 10 minutes until the mixture is uniform.

[0030] The batching and canning of alloy powder are carried out in a vacuum glove box to reduce the contact between alloy elements and air and avoid oxidation. After the filling is completed, it is necessary to vacuumize the ball mill tank and fill it with high-purity argon to reduce the influence of harmful gas elements during the ball milling process. The mixed powder is mechanically alloyed, that is, ball milling for 30 minutes, intermittent cooling for 12 minutes, and then reverse operation for 30 minutes. The ball rotation rate is 350rad / min, the ball-to-material ratio is 30:1, and the steel t...

The alloy powder particles are spherical, the particle size is 15-50 microns, and the oxygen content is 0. 09%-0.14%. The preparation method of the Ti-Al-based amorphous alloy material comprises the following steps of (1), selecting the alloy material powder with the corresponding content, putting the selected alloy material powder into a powder mixer, and uniformly mixing the selectedalloy material powder; and (2), carrying out mechanical alloying on the uniformly-mixed alloy powder material by using a ball milling method so as to prepare a finished product of the alloy material.The Ti-Al-based amorphous alloy powder material is used for a metal 3D printer to 3D print parts.

Description

technical field [0001] The invention relates to the field of metal powder preparation, in particular to a Ti-Al-based amorphous alloy powder material, a preparation method and an application thereof. Background technique [0002] Currently, one of the problems facing 3D printing technology is the shortage of raw materials, especially for metal 3D printing. At present, there are few types of materials available for metal 3D printing, unstable performance, and high temperature resistance of finished products, which have become bottlenecks restricting the development and application of 3D printing technology. The metal powder materials used in traditional powder metallurgy cannot fully adapt to the 3D printing process. [0003] Ti-Al-based alloys mainly include α-Ti 3 Composed of Al phase and γ-TiAl phase, it has the characteristics of high specific strength and specific modulus, high temperature creep resistance and high temperature oxidation resistance, etc. It is a very po...
