Exploration and application of titanium alloy for future innovative development

I. Overview of titanium alloy industry
Titanium is known as the "metal of the future" because of its excellent characteristics. Titanium at room temperature will quickly form a layer of dense oxide film, which makes it has good corrosion resistance, at room temperature almost does not react with acids, alkalis, chlorides. The melting point of titanium is as high as 1,660°C, which gives it a good resistance to high temperatures and allows it to maintain a certain degree of strength even at high temperatures.
Titanium alloy is an alloy composed of titanium based on the addition of other elements such as aluminum, tin, vanadium, molybdenum, niobium, etc. It has excellent properties such as high specific strength, strong fatigue resistance, good corrosion and heat resistance, etc., and it has a wide range of applications in the fields of chemical industry, aviation and aerospace, shipbuilding, marine engineering, metallurgy, sports and leisure.
According to the type and content of alloying elements, titanium alloys can be categorized into α-type titanium alloys, β-type titanium alloys, α+β-type titanium alloys, and near-β-type titanium alloys. According to different processing methods, titanium alloys can be divided into ingots, forgings, plates, rods, tubes, wires and other forms.
According to different application requirements, titanium alloys can be made into various parts or equipment, such as aircraft structural parts, engine parts, missile parts, artificial joints, dental implants, surgical instruments, etc., which play an important role in improving biocompatibility and antimicrobial properties.

Second, the development of titanium alloy industry
Up to now, China has become one of the world's largest producers of titanium metal, titanium alloy has been widely used in aviation, aerospace, military, nuclear energy, medical, marine and other fields, known as aerospace and modern warships, "noble metal".
Titanium alloy is one of the main structural materials for aircraft and spacecraft engines, and the main demand for titanium in China is for the chemical industry and aerospace, of which the demand for titanium in the aerospace field is gradually rising. According to statistics, in 2011, China's titanium in the aerospace field accounted for 8.3%, 2021 accounted for 18%. According to China's titanium industry development report, China's aerospace titanium production CAGR of 21.84% in 2015-2021, the industry production and sales continue to rise.
In the United States, Russia and other developed markets in the aerospace titanium consumption accounted for even more than 70%, Boeing, Airbus and other commercial aircraft manufacturers is one of the largest sources of demand. China's chemical use of low-end titanium material is more, aviation with high-end titanium material market there is still a large potential, with the upgrading of domestic military aircraft and new models installed, as well as commercial aircraft through the airworthiness certification after the release of production capacity, the future of high-end titanium alloy materials market space is vast.
According to research and analysis, the use of titanium alloy materials in the field of consumer electronics can significantly improve the structural strength of the product, in the folding screen cell phone has become an industrial trend in the background, the screen hinge using titanium alloy materials can significantly improve the service life of the use of titanium alloy materials will also significantly reduce the weight of consumer electronics products.
Third, the development trend of titanium alloy industry
With the development of the economy, all industries need to constantly replenish new equipment to meet the changing market demand. In addition, due to the superiority of the products of titanium alloy and its scarcity in some specific areas, so its demand is increasing, becoming a very important part of the industry. Sustainable development has become an important theme for the manufacturing industry to harmonize with nature and society, and the concept of green development has gradually become a consensus.
High-end titanium alloy production enterprises began to pay attention to green technology in product process development and design, production and manufacturing, innovation, high efficiency, energy saving, environmental protection and recyclable new manufacturing processes and equipment, and constantly reduce resource consumption and environmental impact, to achieve the coordination and optimization of the enterprise's economic and social benefits. Green is an inevitable trend in the development of high-end titanium and titanium alloy products processing technology.
With the implementation and promotion of the national "14th Five-Year Plan", the titanium alloy industry will face new development opportunities and challenges. In the future, the titanium alloy industry will pay more attention to technological innovation and industrial upgrading, and promote the synergistic development of the upstream and downstream of the industrial chain. At the same time, the titanium alloy industry will also actively respond to the challenges of globalization and market competition, strengthen international cooperation and exchange, and jointly promote the sustainable development of the titanium alloy industry.
