1、 Microstructure and phase composition
TC25 titanium alloy belongs to the α+β type titanium alloy, and its microstructure is composed of both the α phase (close packed hexagonal structure) and the β phase (body centered cubic structure). This structure endows the material with high strength, good plasticity, and toughness. By adjusting the heat treatment process, its phase composition and microstructure can be further optimized to meet the needs of different application scenarios.
2、 Mechanical properties
TC25 titanium alloy exhibits excellent thermal strength and heat resistance due to its unique chemical composition and the addition of high melting point elements. At higher temperatures, it can still maintain good strength and hardness. In addition, the alloy also has high yield strength and tensile strength, as well as good fracture toughness and fatigue life, making it an ideal material for high-temperature environments in aerospace, energy and other fields.
3、 Hot processing and welding performance
TC25 titanium alloy has good hot workability and can be formed through processes such as forging, rolling, and extrusion. During the hot processing, it is necessary to strictly control the heating temperature, deformation rate, and cooling conditions. Welding is one of the key technologies for connecting TC25 titanium alloy components. Choosing appropriate welding methods and parameters, as well as taking appropriate preheating and post weld heat treatment measures, can effectively improve the quality and performance of welded joints.
4、 Corrosion resistance
TC25 titanium alloy exhibits excellent corrosion resistance in various corrosive environments, mainly due to its stable passivation film and lower corrosion rate. In marine environments, acidic media, and high-temperature oxidation environments, this alloy can maintain good corrosion resistance, thereby extending the service life of components. In addition, titanium alloys have excellent biocompatibility and are therefore widely used in fields such as medical implants.
In summary, TC25 titanium alloy plays an important role in aerospace, high-temperature environment applications, and other fields due to its unique chemical composition, excellent comprehensive performance, and wide application prospects
