superalloys is an alloy that exhibits excellent mechanical
strength and creep resistance at high temperatures, good
surface .

Answer / yesm

superalloys are use for high temp.application.

Answer / vishalshah007

super alloy is a metallic alloy with high mechanical
strength & resistance to surface degradation at high temp
(above 650'c).

Typically having a matrix with an austenitic, FCC crystal
structure.

Stable alloy with resistance to deformation & high
temperature strength.

In superalloys, oxidation & corrosion resistance is provided
by formation of protective oxide layer which is formed when
the metal get exposed to oxygen & encapsulates the material
& thus protecting the rest of component

Moat important strenthning mechanism is through the
formation of secondary phase precipitates such as gamma
prime and carbides through precipitation strenthening.

The 3 major classes of super alloys are:
~Nickel based super aloys
~Iron based super alloys
~Cobalt based super aloys
