Abstract

The invention discloses a high-temperature-resistant titanium alloy material for 3D printing. According to the high-temperature-resistant titanium alloy material, a titanium alloy is matched with an amorphous metal, the temperature resistance, strength and toughness are improved through doping titanium carbide ceramic, and the amorphous metal has a structure crystallization tendency when a temperature rises, so that the titanium alloy has no creep deformation under a high-temperature condition of 650 DEG C, thus the defect of no high-temperature resistance of metal products subjected to titanium alloy 3D printing is overcome. An application of manufacturing high-temperature-resistant complex equipment such as a titanium alloy engine by virtue of a 3D printing technology is further promoted.

Description

technical field [0001] The invention belongs to the field of 3D printing and manufacturing, and relates to 3D printing materials, in particular to a high-temperature-resistant titanium alloy material for 3D printing. Background technique [0002] "3D printing" is a popular name, and its academic name is "Rapid Prototyping & Manufacturing", which is a forming principle that uses material accumulation. The rapid prototyping system is like a "three-dimensional printer", which can quickly and precisely manufacture new product samples of any complex shape without the need for traditional tools, machine tools, and fixtures. 3D printing technology is an advanced manufacturing technology developed by the multidisciplinary integration of information technology, new material technology and high-end manufacturing technology. It not only overcomes the loss caused by traditional subtractive manufacturing, but also makes product manufacturing more intelligent, more accurate and more effic...
