PWA 1480(Ni-Cr-Ta-Co)

1. Introduce – The first production single crystal alloy – Single crystal (SC) only alloy – Improved melting point of the alloy without adding grain boundary strengthening elements – Full employment of coarse-grained precipitation γ’ phase by high-temperature solubilization treatment, and fine re-precipitation is possible * PWA Alloy : Mainly applied to airfoil (or airfoil) compressor blades of turbine engine fans * Single crystal (SC) : A solid in which the entire crystal is regular along the crystal axis * Solubilization treatment : Heating to a temperature wher...
