Key Features:

• Behavior of the Material: Creep resistance, thus, ensures that metals and alloys retain the structural integrity and mechanical properties for extended periods of time under thermal and mechanical stress.
• Influencing Factors: The material properties that resist creep may depend an awful lot on the condition of the grain structure within. The alloy composition, thermal conditions, and various strengthening techniques (like precipitation hardening and grain boundary strengthening) increase creep resistance.
• Testing & Measurement:  Tests such as the creep rupture, stress relaxation, and constant load tests are the ones that engineers perform to ascertain the crossover point beyond which the given material can endure operating conditions.

Creep resistance is extremely important to industries that operate such materials under extreme temperatures and long-held stress. Nickel-based superalloys, which are considered to possess high-strength creep resistance, are required to be used for long-term safe performance in jet engines and gas turbines. In power plants, heat-resistant steels prevent structural failures from occurring to the boiler tubing. Meanwhile, creep-resistant materials continue to improve due to advances in metallurgy such that new alloys and coatings have been and are still being developed in order to sustain function in high-temperature applications.
