摘要： One aspect relates to a method for producing an alloy characterized by grinding tantalum to form a tantalum powder and grinding tungsten to form a tungsten powder; mixing the tantalum powder and the tungsten powder to form a blended powder. The weight fraction of tungsten powder in the blended powder is larger than in the desired alloy. A blended body is produced from the blended powder by a powder metallurgical route. A pre-alloy is produced by a first melting of the blended body and at least a fraction of at least one further metal by a melt metallurgical route. The alloy is produced by a second melting of the pre-alloy and the remaining fraction of at least one metal by a melt metallurgical route.

摘要： One aspect relates to 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.The method according to one embodiment is characterized by 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 the weight fraction of tungsten powder in the blended powder is larger than in the desired 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 the remaining fraction of at least one metal by means of a melt metallurgical route.
