At high temperatures, titanium metal will deform, but it will not burn out of shape.
1. High temperature resistance of titanium metal
Titanium metal has excellent mechanical properties and good corrosion resistance, and is widely used in high-end equipment, aerospace, and other fields. However, the performance of titanium metal at high temperatures is worthy of attention.
Titanium metal will undergo changes such as lattice structure changes and solid solution phase decomposition at high temperatures, which will affect its performance. Titanium alloys are generally considered to have excellent high-temperature strength and good creep resistance below 450°C, but beyond this temperature range, their mechanical properties will decrease rapidly.
2. Deformation of titanium metal
At high temperatures, titanium metal is prone to deformation, mainly in the following aspects:
1. Creep deformation
Creep refers to the deformation of materials under high temperature and high stress, including matrix creep, high stress creep, and other types of creep that only occur at high temperatures. Titanium metal is prone to creep deformation at high temperatures, which affects its mechanical properties and shape stability.
2. Thermoplastic deformation
At high temperatures, titanium is also prone to thermoplastic deformation. During the hot working process, the shape and size of titanium are difficult to control, and necessary shape corrections are required.
3. Thermal expansion
The thermal expansion coefficient of titanium is relatively large, and it is easy to expand and deform when in a high-temperature environment.
In summary,
Titanium is easy to deform at high temperatures, but it will not burn out. Therefore, when using titanium, its use temperature must be controlled, and processing control and shape correction must be paid attention to during the manufacturing process to ensure its mechanical properties and shape stability.
