Materials required in the aerospace sector need to have the ability to work consistently and stably in environments of 600-1100°C, and high-temperature alloys are undoubtedly one of the best choices. High-temperature alloys are also known as heat-strong and heat-stable alloys due to their good strength and heat resistance. Thermal strength is mainly manifested in creep resistance and fatigue resistance, thermal stability is mainly manifested in good oxidation resistance and resistance to corrosion of high temperature gases.
