Abstract

A method for the additive manufacturing of a component includes providing a powdered base material for a component, in particular a component for the hot gas path of a gas turbine, building up the component layer by layer on a building platform by fusing individual layers of the base material, and introducing an oxide dispersion strengthening into a region of the component to be additively manufactured by an oxidic additive, wherein the region is usually exposed to high thermomechanical loading during operation of the component.
