Abstract
The disclosure relates to a powder and a method for generating a component by a powder-bed-based additive manufacturing method, such as laser melting. The powder includes particles having a core and a shell. The particles have an alloy composition of the component. The concentration of higher-melting alloy elements is greater in the shell and the concentration of lower-melting alloy elements is greater in the core, wherein the surface of the particles is higher in comparison with particles with a constant alloy composition. This advantageously prevents the particles from caking together in the powder bed during the production of the component, and so the powder bed may also be subjected to high preheating temperatures of up to 1000° C.
