Performance of titanium plates in high or low temperature environments

1. Performance in high temperature environments
Strength and stability
Titanium plates have excellent strength and stability at high temperatures. For example, the long-term operating temperature of TA1 pure titanium can reach 300°C, while some high-temperature resistant titanium alloys such as Ti-6Al-4V can still maintain their mechanical properties for a short time when the temperature reaches 540°C. Under long-term application, the recommended operating temperature range is 450-480°C.
Titanium plates are not prone to deformation or embrittlement at high temperatures. Its strength gradually decreases with increasing temperature, but within a reasonable temperature range, it can still maintain sufficient strength and stability to meet various application requirements.
Corrosion resistance
Titanium plates have outstanding corrosion resistance to most chemical media at high temperatures. Its surface can generate an extremely thin, dense and stable oxide film, which has an anti-oxidation protection effect. However, it should be noted that titanium plates may be sensitive to stress corrosion when in contact with certain media (such as dry sodium chloride) at high temperatures.
Heat treatment and cooling
When the titanium plate is cooled at high temperature, if the cooling speed is too fast, residual stress may be generated inside it, making it brittle. Therefore, it is necessary to take reasonable cooling process and heat treatment measures, such as annealing and aging treatment, to eliminate or reduce residual stress and improve the toughness of the titanium plate.

2. Performance in low temperature environment
Strength and toughness
In low temperature environment, the strength of the titanium plate gradually increases while maintaining its original plasticity and toughness. This feature makes the titanium plate an ideal low-temperature engineering material. For example, in a low temperature environment of -196°C, the titanium sheet plate will not show low-temperature brittleness.
Some titanium alloys such as Ti-5AI-5SnELI perform well in low temperature environments. Their strength increases with decreasing temperature, while the plasticity decreases relatively little, so they can still maintain excellent ductility and toughness under ultra-low temperature conditions.
Stability
Titanium plates have good stability at low temperatures and are not prone to deformation or cracking. This makes titanium plates widely used in storage and transportation containers for cryogenic liquids such as liquid oxygen and liquid hydrogen.

3. Application cases of titanium plates in high and low temperature environments
Application in high temperature environments
Titanium plates are widely used in high temperature equipment and aero engines due to their excellent high temperature performance. For example, in aero engines, titanium plates are used to manufacture key components such as compressor disks and blades, which can withstand the harsh environment of high temperature and high pressure.
Application in low temperature environments
In low temperature environments, titanium plates are used to manufacture storage and transportation containers for cryogenic liquids such as liquid oxygen and liquid hydrogen. In addition, titanium plates are also used in building materials in cold areas due to their good low temperature performance.

4. Comparison with other materials
Compared with other metal materials, titanium plates have better performance in high and low temperature environments. For example, compared with aluminum alloys and magnesium alloys, titanium plates have higher strength and stability at high temperatures; compared with stainless steel, titanium plates have better toughness and impact resistance at low temperatures.
