Abstract

One aspect is a method for producing an alloy, whereby the alloy includes at least a first metal and a second metal, whereby firstly a powder metallurgical route and subsequently a melt metallurgical route is used sequentially in order to generate the alloy from the, at least, first metal and the second metal. The method includes grinding the first metal into a first metal powder, grinding the second metal into a second metal powder, mixing the first metal powder and the second metal powder to produce a blended powder, generating a blended body from the blended powder by the powder metallurgical route, and generating the alloy by melting the blended body by the melt metallurgical route.
