Certain applications require the ability of the structure to resist high temperatures, such as aircraft with high thermal loads (due to high speeds, high engine temperatures, low idling times, and airborne equipment such as lasers), space shuttles (especially during the return to the Earth ’s atmosphere), Exchangers (as related to water heaters), brakes (heating due to friction that occurs during braking), components (welding due to heat during welding), microelectronic components (during operation, due to current in the circuit and welding) It heats up during the process), battery components (heating during operation due to current through the battery), asphalt roads (heating due to tire friction and sunlight), and medical implants (heating due to body temperature). Generally, the elevated temperature is above room temperature on average. For space shuttles, aircraft friction brakes, and welded parts, the elevated temperature can be as high as 1000 degrees Celsius or higher. However, for asphalt roads and medical implants, the high temperature is just a little over temperature. Despite the wide range of high temperature variations, the issue of high temperature resistance is important for all these applications.
