Nickel-based superalloys are an unusual class of metallic materials

with an exceptional combination of high temperature strength,

toughness, and resistance to degradation in corrosive or oxidizing

environments. These materials are widely used in aircraft and

power-generation turbines, rocket engines, and other challenging

environments, including nuclear power and chemical processing plants.

Benefits:

l  Highly spherical

l  Low oxygen content and no contaminants

l  Highly flowability

l  Good corrosion resistance

l  Tailored size distribution

Nickel-base superalloys consists of the gamma matrix, and

of intermetallic γ' precipitates. The γ-phase is a solid solution

with a face-centered crystal (fcc) lattice and randomly distributed

different species of atoms. By contrast, the γ'-phase has an

ordered crystalline lattice of type LI₂. Modern alloys typically

contain about 70% by volume fraction of cube-like γ' precipitates

whose edge length is about 0.5 μm
