The invention aims to solve the technical problems that the discontinuous reinforced titanium-based composite material has poor reinforcing effect and high room temperature brittleness, and the traditional smelting technology has serious segregation and poor tissue uniformity. According to the invention, a low-energy ball milling method is adopted, so that TiB 2 powder is uniformly adhered to the surfaces of Ti 2 AlNb prealloy powder particles, and reasonable ball milling parameters are selected, so that the Ti 2 AlNb powder maintains good sphericity in the powder mixing process; then in-situ autogenous reaction promotes TiBw to grow near the surface of the spherical matrix alloy in the hot-press sintering process, so that further growth of crystal grains can be limited, a uniform network structure can be obtained, and the network structure can inhibit growth of the crystal grains in the sintering process, so that the Ti 2 AlNb-based composite material with excellent room temperature performance is obtained.
Description
Technical Field
The invention relates to a preparation method of a Ti 2 AlNb-based composite material.
Background
The new generation of aircraft has higher thrust-weight ratio of engines, and meets the requirement of long-time high-temperature environment service, while the Ti 2 AlNb alloy has excellent high-temperature performance, higher specific strength and good room-temperature plasticity, and is mainly applied to high-temperature parts on the engines of aerospace aircrafts. However, as an intermetallic compound, the plasticity of the Ti 2 ainb alloy cannot meet the requirements of the new generation of aircrafts, which also limits the wide application of the Ti 2 ainb alloy in the fields of aerospace and automobile engines. In order to further improve the room temperature performance of the Ti 2 AlNb alloy, the ceramic reinforcing phase can be introduced into the matrix alloy by utilizing the characteristics of high strength and high rigidity of the ceramic material through an in-situ autogenous or externally-added method, so that the Ti 2 AlNb-based composite material with excellent performance is obtained.
The discontinuous reinforced metal matrix composite material has the advantages of higher specific strength, higher specific rigidity, higher heat resistance limit and the like compared with the matrix alloy. Japanese scholars Emura et al first introduced in-situ authigenic boride reinforcing phases into Ti 2 AlNb alloys to prepare discontinuous reinforced Ti 2 AlNb-based composites. The reinforcing phase has a very good reinforcing effect, and the high-temperature mechanical property of the Ti 2 AlNb-based composite material is obviously improved; in the research process of reinforcing Ti 2 AlNb-based composite materials by boride, american scholars Cowen and the like find that reducing the size of a reinforcing phase and improving the compactness of the materials are key for improving the comprehensive mechanical properties of the composite materials. However, according to the conventional studies, the strength of the Ti 2 ainb alloy was greatly increased by introducing a high-strength reinforcing phase, and the plasticity was greatly lowered.
Because the difference of melting points of Ti, al and Nb is large, the boiling point of Al element is far lower than that of Nb element, and the phenomena of serious volatilization of Al element (the mass fraction of volatilized burning loss reaches 5% -10%) and serious segregation of Nb element occur in the Ti 2 AlNb-based alloy in the smelting and casting process, the indexes such as the accuracy of the final alloy components, the uniformity of the structure, the compactness of the alloy cast ingot and the like are difficult to ensure. Compared with the traditional smelting method, the powder metallurgy method can obtain a uniform microstructure without segregation phenomenon.
Disclosure of Invention
The invention aims to solve the technical problems of poor reinforcing effect and high room temperature brittleness of a discontinuous reinforced titanium-based composite material, serious segregation and poor tissue uniformity of the traditional smelting technology, and provides a preparation method of a Ti 2 AlNb-based composite material with excellent room temperature plasticity.
The preparation method of the Ti 2 AlNb-based composite material with excellent room temperature plasticity is carried out according to the following steps:
TiB 2 particle powder is used as a reinforcing phase, ti 2 AlNb prealloy powder is used as a matrix alloy, tiB 2 particle powder and Ti 2 AlNb prealloy powder are poured into a ball milling tank together for ball milling and mixing, the mixed powder is packaged in a graphite mold after ball milling is finished, then the graphite mold is placed into a vacuum hot-pressing sintering furnace for vacuumizing to avoid powder oxidation pollution caused by contact with air, sintering is carried out for 1h to 5h under the conditions that the sintering temperature is 1250 ℃ to 1330 ℃ and the sintering pressure is 30MPa to 45MPa, and the TiBw/Ti 2 AlNb-based composite material is obtained after the sintering is finished and then cooled along with the furnace;
The mass of the TiB 2 particle powder is 0.1-0.2% of the sum of the mass of the TiB 2 particle powder and the mass of the Ti 2 AlNb pre-alloy powder.
The TiBw/Ti 2 AlNb-based composite material with excellent room temperature plasticity is prepared by adopting a preparation method of low-energy ball milling and vacuum hot-pressing sintering and combining an in-situ self-generating reaction technology. The formula of in-situ autogenous reaction of Ti and TiB 2 is Ti+TiB 2 =2TiB, firstly, a low-energy ball milling method is adopted to ensure that TiB 2 powder is uniformly adhered on the surfaces of Ti 2 AlNb prealloy powder particles, and reasonable ball milling parameters are selected to ensure that the Ti 2 AlNb powder is not deformed in the powder mixing process, so that better sphericity is maintained; then in-situ self-generating reaction promotes TiBw (TiB whisker) to grow near the surface of the spherical matrix alloy in the hot-press sintering process, so that further growth of crystal grains can be limited, a uniform three-dimensional reticular structure is obtained, the reticular structure has a very good grain boundary strengthening effect, and the TiBw strengthening phase of in-situ self-generating reaction can be connected with adjacent titanium crystal grains like pins to coordinate integral deformation of the material, and can effectively improve the plasticity and toughness of the composite material; the mesh structure can inhibit the growth of crystal grains in the sintering process; the three-dimensional network structure has the characteristic of introducing a ceramic phase into a grain boundary, can achieve the aim of improving the room temperature plasticity of the composite material, and obtains the TiBw/Ti 2 AlNb-based composite material with excellent room temperature performance, wherein the tensile strength is more than 1050MPa, and the elongation is more than 12%.
The invention is based on the design principle of damage tolerance, and improves the room temperature plasticity of the Ti 2 AlNb-based composite material as much as possible while maintaining the same strength, thus obtaining the Ti 2 AlNb-based composite material with excellent strong plasticity matching.
