Nickel Based Superalloys - University of Cambridge

Strength versus Temperature. The strength of most metals decreases as the temperature is increased, simply because assistance from thermal activation makes it easier for dislocations to surmount obstacles. However, nickel based superalloys containing γ', which essentially is an intermetallic compound based on the formula Ni 3 (Al,Ti), are particularly resistant to temperature.
