Description
Technical Field
The invention relates to the technical field of additive manufacturing, in particular to a wire additive manufacturing method of a titanium alloy single crystal blade.
Background
The technical level of an aero-engine as a pearl on an industrial crown is an important mark for measuring national science and technology, industry and comprehensive national strength. Due to the specific requirements of aircraft engines, they are required to be able to withstand high temperature, high strength environments with low mass. The nickel-based single crystal blade is commonly used at the high-temperature end of an aeroengine due to excellent high-temperature mechanical properties, the low-temperature end uses a light high-strength titanium alloy polycrystalline blade, and a nickel-based single crystal material is still used in a high-temperature and low-temperature transition region in order to ensure safety.
With the continuous improvement of the thrust-weight ratio of an aeroengine, the performance of each part tends to be limited, a high-temperature end nickel-based single crystal cannot be replaced, a low-temperature end titanium alloy is still the most ideal high-specific strength material, and the material in a high-temperature and low-temperature transition region still has a promotion space. The problem can be effectively solved by using the titanium-aluminum alloy in the area, but the titanium-aluminum alloy is difficult to process due to room temperature brittleness and is not beneficial to popularization. The titanium alloy single crystal blade has excellent high-temperature performance due to elimination of crystal boundaries, can be used for replacing materials in high and low temperature transition regions of an aeroengine, further reduces the quality of the aeroengine, and has important significance for promoting the development of the aeroengine.
The traditional method of manufacturing single crystal structural members is investment casting, which, like the method of manufacturing nickel-based single crystal blades, requires ceramic molds to be shaped. However, titanium alloys are very reactive in chemical properties at high temperatures, and can chemically react with ceramic molds, and reaction products can contaminate raw materials and even can crack after solidification, so that they are not suitable for the manufacture of single crystal structural members. The investment casting method for manufacturing the single crystal achieves the growth condition of the single crystal by controlling the solidification behavior of a solid-liquid full interface, and realizes the manufacturing of the single crystal. The traditional full-interface regulation and control method has the advantages that the temperature field is controlled simply when the structure is small, and the full-interface regulation and control of the temperature field becomes difficult when the structure is large, so that the equipment requirement is extremely high. Therefore, the method for realizing single crystal growth by full interface regulation has two fatal problems when a large single crystal structural member is manufactured, and firstly, the method for regulating and controlling the full solid-liquid interface is difficult to control the manufacturing of the large single crystal structural member; second, the size and cost of the mold and temperature field controlled equipment will increase dramatically.
The method without the die is a suspension smelting method, but the method can only be used for manufacturing a solid rod-shaped structural part, has a single shape, needs complex secondary processing for the structural part with a complex shape, and is long in time and high in cost.
The additive manufacturing technology is not sensitive to the size of the structural part, because the additive manufacturing technology is created for the die-free manufacturing, and the direct deposition method in the additive manufacturing can be free from the limitations of powder beds and the like, the manufacturing of large structural parts is realized, and the preparation capability of the large structural parts is provided, so the additive manufacturing technology has good prospect and application in the die-free manufacturing aspect, and a new method for manufacturing single crystal structural parts is possibly developed. The principle of metal additive manufacturing is to melt raw materials by a heat source for stacking and forming, wherein the heat source mainly comprises laser, electron beams and electric arcs. The raw materials of the current mature method are metal powder, but the metal powder can generate a large amount of splashed liquid drops in the manufacturing process, and once the splashed liquid drops are attached to a single crystal structural member in the manufacturing process, mixed crystals are inevitably introduced, and the method is almost inevitable.

step one; the shape of the single crystal rod 6 is designed to establish a three-dimensional solid model of the single crystal rod 6.
Step two; after the three-dimensional solid model of the monocrystalline rod 6 is subjected to picture slicing processing, the three-dimensional solid model is led into an equipment control system;

The titanium alloy single crystal blade 4 is sufficiently sized to be processed into a blade for use in an aircraft engine to enable the manufacture of a titanium alloy single crystal blade.
The terms referred to in this application are to be interpreted as follows:
mixed crystals: is a mixed crystal if an unwanted crystal appears during the manufacturing process, as opposed to a single crystal.
Single crystal substrate: a metal plate having only one crystal grain is used as a starting material for ensuring epitaxial growth in the early stage of growth of a single crystal blade.
And (3) epitaxial growth: the material is formed by arranging molecules according to a certain regular lattice, generally, solidified material is used as basic material, and in the process of crystal growth, if liquid or gaseous molecules can be enabled to continue to grow on the basic material according to the lattice arrangement mode of the basic material, the epitaxial growth is carried out.
Scanning speed: the heat source and wire feeder are relative to the speed of the processing location.
Remelting: the earlier melted material is melted again after solidification.
α phase and β phase: the melting point of metallic titanium is 1668 ℃, below which the liquid titanium crystals solidify to form beta grains of a cubic-centered structure, which are referred to as beta phase. When the temperature is lower than 882 ℃, solid phase transformation of titanium can occur, namely, alpha phase with a close-packed hexagonal structure is regenerated in the solidified beta phase, and the generation mode of the alpha phase is random and difficult to control.
Alpha titanium alloy, beta titanium alloy, alpha + beta titanium alloy: the melting point and the transformation point of titanium can be changed according to the added alloy elements, so that the internal structure of the finally formed titanium alloy presents three types of titanium alloys with all alpha phases, all beta phases and both alpha and beta phases.
