1 Introduction
Nickel-based superalloys are widely used in propulsion components of the
aerospace industry such as turbine engine blades, disks, casings, and liners. These
superalloys are able to maintain their strength at a range of low to high temperatures,
which allow engines to operate at high efficiency without mechanical failure [1, 2].
Large economic gains can be achieved by improving reliability and life of their
aerospace applications through better predictability of relevant properties. These
alloys possess a desirable combination of high-temperature strength and toughness,
oxidation, creep resistance, and high-temperature stability that is attributed to the
existence of a two-phase γ −γ matrix-precipitate microstructure as shown in Fig. 1.
