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
