Description
Technical Field

Background
The titanium-aluminum intermetallic compound is considered to be one of high-temperature structural materials which are expected to replace Ni-based high-temperature alloys in the new century because of the advantages of high specific strength, specific modulus, good oxidation resistance, creep resistance and the like. However, titanium-aluminum intermetallic compound alloys exhibit poor processability at room temperature due to low mobility of superlattice dislocations and lack of sufficient deformation modes. The current titanium-aluminum intermetallic compounds can only be processed by casting and high temperature plastic forming, and the high manufacturing cost and long manufacturing cycle limit the further application of titanium-aluminum intermetallic compounds.
The additive manufacturing technology is a manufacturing method for forming a three-dimensional solid component by accumulating materials layer by layer from bottom to top based on a material layering accumulation principle, has the advantages of simple process flow, high material utilization rate, high forming efficiency and the like, and is particularly suitable for manufacturing titanium-aluminum intermetallic compounds. The additive manufacturing technology can be divided into three methods of powder paving and selecting area melting, powder feeding melting and deposition and wire feeding melting and deposition according to different manufacturing processes. The invention patent with the publication number of CN110449581A discloses a method for preparing TiAl + Ti by laser melting deposition2The invention discloses a method for forming an AlNb composite material, which adopts a laser powder feeding melting deposition method to form the material, and solves the problem of forming a titanium-aluminum intermetallic compound, but the laser melting technology has higher requirement on the quality of metal powder, the compactness has larger influence on the performance of a member, and the laser deposition rate is lower, so that the application of the AlNb composite material in the preparation of large members is limited.
The method adopting wire feeding melting deposition in the prior art can solve the problems, and the wire feeding melting deposition technology has high processing efficiency and high degree of freedom, and is particularly suitable for preparing large-size components. However, the titanium-aluminum intermetallic compound has poor room temperature plasticity and is difficult to realize wire drawing, so that the feasibility of manufacturing the wire by wire drawing to realize additive manufacturing is extremely low. Three invention patents with the publication numbers of CN110605462A, CN112139650A and CN112139649A relate to a method for preparing intermetallic compounds by melting and depositing a wire, the three invention patents adopt a method of double-wire feeding, and the titanium-aluminum intermetallic compounds are prepared by controlling a double-wire feeding mechanism of titanium wires and aluminum wires. However, the double-wire feeding mechanism increases the equipment cost on one hand, and increases the complexity of the equipment movement mechanism on the other hand, so that the metal deposition path is influenced by problems such as movement interference in the deposition process, the preparation of a metal component with a complex structure is not facilitated, and certain limitations are provided.
