High quality and high performance of additive manufactured (3D-printed) material requires good control of the microstructure of the materials.

Widely employed in aero and energy industry, superalloys have relatively poor machinability, which is not surprising because of their excellent mechanical properties even in demanding environment. Additive manufacturing (AM) provides a near-net shaping solution with excellent precision by depositing materials layer-by-layer. This project focus on the microstructure and mechanical properties of high strength superalloys produced by AM-methods and on process optimisation of the materials manufacturing methods.
