  What are the materials of aircraft engine turbine blades? What are the cooling methods of turbine blades? Turbine blades are an important component of the turbine section in a gas turbine engine. The high-speed rotating blades are responsible for drawing high-temperature and high-pressure air into the burner to maintain the engine's work. Next, let me tell you in detail what are the materials for the turbine blades of the aircraft engine and what are the cooling methods for the turbine blades. 1. What are the materials of aircraft engine turbine blades? A. Deformed high temperature alloy The development of wrought superalloys has a history of more than 50 years. The wrought superalloys commonly used in domestic aircraft engines are mainly Cr-Ni alloy systems and Cr-Ni-Co alloy systems. For details, refer to Table 1. As the content of aluminum, titanium, tungsten, and molybdenum increases in superalloys, the material properties continue to improve, but the hot workability decreases; adding expensive alloying element cobalt can improve the overall properties of the material and improve the stability of the high-temperature structure. B. Cast Superalloys The bearing stability of cast turbine blades increased from about 750°C in the 1940s to about 1700°C in the 1990s. The cast superalloys for blades are shown in Table 2. C. Superplastic forming of titanium alloys At present, the most commonly used titanium alloys for superplastic forming blades are Ti6Al4V and Ti6Al2Sn4Zr2Mo. More titanium alloy materials are shown in Table 3. Although the application of composite materials has a growing trend recently, there are disadvantages that are difficult to solve at this stage, such as: High manufacturing costs , cannot be recycled, and has poor high-temperature performance, so titanium alloys are still the main materials for superplastic form

• Application of titanium alloy in bicycle and auto racing field 2023-01-11

  Application of titanium alloy in bicycle and auto racing field Titanium bicycles have the advantages of light weight, high strength, good corrosion resistance and fatigue resistance. Since the mid-1980s, titanium bicycles have developed rapidly, which has greatly promoted the application of titanium materials. For example, ANCOTECH, HAYNES INTERNATIONAL. and SANDVIK SPECIAl. METALS, three companies producing Ti3Al-2.5V pipes in the United States, have all turned to the bicycle industry. In terms of material selection, Ti-3Al-2.5V and Ti-6Al-4V are the most commonly used titanium alloys for bicycle frames. Compared with other titanium alloys, the biggest advantage of Ti-3Al-2.5V is high yield strength and good process plasticity , and has good welding performance, the disadvantage is the high price. Although it was developed for aircraft hydraulic systems, it meets the material performance requirements of the bicycle market due to its good formability, corrosion resistance and elongation, combined with high fatigue strength and low density. In the past few years, frames made of industrial pure titanium arms and non-aerospace Ti-3Al-2.5V (sports grade) titanium alloys have been popular, and Ti-6AL-4V is the most mature application with relatively good comprehensive mechanical properties. It is the titanium alloy material with the most complete performance data. It has good process plasticity and superplasticity, and is suitable for various pressure processing and forming. It can also be welded and machined in a variety of ways, but the formability, weldability and machining The performance is not as good as the former. In terms of making frame, Ti-6Al-4V is also attractive. It has slightly higher modulus and strength than li-3AL-2.5V, but it is more difficult to process it into small diameter bicycle frame tubing. The crankshaft positioner, pedals, handlebars and other bicycle parts connected to the frame are mostly made of Ti-6Al-

• titanium alloy application QYX titanium 2022-10-11

  Titanium alloy application QYX titanium Titanium and its alloys have been widely used in more and more fields because of their superior properties: 1 . application in hydrometallurgy industry As a new corrosion resistant material, titanium has been used for more than 20 years in the metallurgical industry,especially in the hydrometallurgy industry of China. However,it has achieved great success and achieved remarkable social and economic benefits. From the beginning of 70s, Yunnan smelter, Shanghai smelter,Huludao zinc plant and other non-ferrous metallurgical industry pioneered the use of titanium material in electrolytic copper, electrolytic nickel and zinc smelting, to solve the serious corrosion problem plagued production and development of titanium and titanium equipment in the application of the success of the enterprise, but also promote the use of China' s Titanium Industrial
