Abstract

The present disclosure relates to powder-bed-based additive manufacturing processes. Embodiments thereof may include methods for producing a component from a superalloy. For example, a method for producing a component comprising a superalloy may include: preheating a powder bed comprising particles of a core material coated by a ceramic layer, the core material including alloying constituents of the superalloy and building up the component layer by layer in a powder bed by melting particles with an energy beam. The powder bed may be heated to a temperature below a melting point of the core material before the particles are melted.
