Nickel superalloy jet engine turbine blade A superalloy , or high-performance alloy , is an alloy with the ability to operate at a high fraction of its melting point. [ 1 ] Key characteristics of a superalloy include mechanical strength , thermal creep deformation resistance, surface stability, and corrosion and oxidation resistance.
Inconel is a nickel-chromium-based superalloy often utilized in extreme environments where components are subjected to high temperature, pressure or mechanical loads. Inconel alloys are oxidation- and corrosion-resistant. When heated, Inconel forms a thick, stable, passivating oxide layer protecting the surface from further attack.
Mechanical alloying is akin to metal powder processing, where metals may be mixed to produce superalloys. Mechanical alloying occurs in three steps. First, the alloy materials are combined in a ball mill and ground to a fine powder. A hot isostatic pressing (HIP) process is then applied to simultaneously compress and sinter the powder.
In 2007, the company purchased Cherry Aerospace to expand their fastener business.
