Alloys
In space and astronautical engineering, alloys refer to metallic materials composed of two or more elements, at least one of which is a metal. Alloys are used extensively in the construction of spacecraft and their components due to their desirable properties such as high strength, durability, and resistance to corrosion and extreme temperatures. The selection of alloys for specific applications depends on the requirements of the mission and the environment in which the spacecraft will operate. For example, titanium alloys are commonly used in the construction of rocket engines and structural components due to their high strength-to-weight ratio and resistance to corrosion. Aluminum alloys are often used in the construction of spacecraft structures due to their low density and high strength. Nickel-based superalloys are used in the construction of turbine blades for rocket engines due to their ability to withstand high temperatures and stresses.
