Additive Manufacturing of Superalloys

Additive manufacturing enables integrated part manufacture of superalloy parts, especially for the aerospace and power industries. The investments required to realize these parts are huge due to the number of iterative optimizations required at the as-built stage for flawless parts coupled with the challenges of minimal distortion, static and cyclic mechanical properties, and creep strengths. The understanding of non-equilibrium physics, solidification processing routes, metallurgy and computational simulation is therefore essential to enable designers, researchers and practitioners to design and develop superalloy parts.
