Superalloy without titanium, powder, method and component
A nickel-based superalloy without titanium and a corresponding powder. A process for producing a component, wherein the alloy or the powder is used, in particular for a process for additive manufacture, especially selective laser sintering or selective laser melting. A component having an alloy or produced from the powder or produced by the process.
