High-temperature Alloys
High-temperature alloys are a class of materials that exhibit excellent mechanical strength and resistance to creep, oxidation, and corrosion at elevated temperatures. These alloys are typically used in extreme environments such as gas turbines, rocket engines, and nuclear reactors, where they are subjected to high temperatures, pressures, and stresses. High-temperature alloys are composed of a variety of elements, including refractory metals such as tungsten, molybdenum, and niobium, as well as nickel, cobalt, and iron. These alloys are often strengthened through the addition of secondary phases such as carbides, borides, and intermetallics. The development of high-temperature alloys has been critical to the advancement of space and astronautical engineering, enabling the design and construction of high-performance engines and propulsion systems that can withstand the extreme conditions of space travel.
