Abstract:
1. A method for producing an alloy, whereby the alloy consists of three metals and the three metals are selected from the group consisting of tantalum, tungsten, and niobium, characterized in that the method includes the steps of: a) grinding the tantalum to form a tantalum powder and grinding the tungsten to form a tungsten powder; b) mixing the tantalum powder and the tungsten powder to form a blended powder, whereby a weight fraction of tungsten powder in the blended powder is larger than in the alloy; c) producing a blended body from the blended powder by means of a powder metallurgical route; d) producing a pre-alloy by means of a first melting of the blended body and at least a fraction of at least one further metal by means of a melt metallurgical route; and e) producing the alloy by means of a second melting of the pre-alloy and a remaining fraction of at least one metal by means of a melt metallurgical route.
