Problems solved by technology

Tungsten, molybdenum, niobium, tantalum, vanadium, zirconium, rhenium and other elements can be infinitely fused with titanium to form alloys, but at present, these alloys generally have certain quality problems, because these elements have higher melting points and higher densities than titanium, so Inhomogeneity occurs during smelting to prepare ingots

Description

technical field [0001] The invention relates to the field of metal alloy materials, in particular to a high melting point titanium alloy and a preparation method thereof. Background technique [0002] Titanium is an important structural metal developed in the 1950s. Titanium alloys are widely used in various fields because of their high strength, good corrosion resistance, and high heat resistance. Many countries in the world have recognized the importance of titanium alloy materials, researched and developed them one after another, and obtained practical applications. In the 1950s and 1960s, it mainly developed high-temperature titanium alloys for aero-engines and structural titanium alloys for airframes. In the 1970s, a batch of corrosion-resistant titanium alloys were developed. Since the 1980s, corrosion-resistant titanium alloys and high-strength titanium alloys have been further developed. develop. Titanium alloys are mainly used to make aircraft engine compressor co...
