1. A process for additive manufacture of a component, comprising:
providing a pulverulent base material for the component,
layerwise building up of the component on a building platform by solidification of individual layers of the base material, and
introducing oxidic dispersion strengthening into a region of the additively manufactured component by an oxidic additive, where the region is usually subjected to high thermomechanical stress during operation of the component
wherein the introducing of the oxidic dispersion strengthening is carried out layerwise, by the component being built up at least partially layerwise alternately from the base material and a mixture of the base material and the oxidic additive for formation of the oxidic dispersion strengthening.
