High-temperature Strength

High-temperature strength is the ability of a material to withstand mechanical stress at high temperatures without significant deformation or failure. In the context of space and astronautical engineering, high-temperature strength is a critical property for materials used in the construction of spacecraft and their components, such as engines, heat shields, and re-entry vehicles. Materials with high-temperature strength are able to maintain their structural integrity and perform their intended functions even when exposed to extreme temperatures, such as those encountered during atmospheric re-entry or in the vicinity of a high-temperature heat source. High-temperature strength is typically measured using a combination of tensile, compressive, and shear tests at elevated temperatures, and is influenced by factors such as material composition, microstructure, and processing history.
