Abstract
A method for producing metallic semifinished products such as strip or wire rom metallic work materials which have a high melting point and are difficult to shape, comprising the steps of a) first, alloying at least one element for lowering the melting point with a material that has a high melting point and is difficult to shape; b) then, producing the semifinished product from the alloy with the reduced melting point in the form of strip or wire directly from the melt by quick solidification; and c) finally extracting the elements alloyed with the material in method step a) from the semifinished product by heat treatment in a reactive atmosphere.
