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 is a method for the production of a three-dimensional structure of successive layers producing a multitude of successive layers wherein, with the exception of a first layer, each of the successive layers is arranged on a preceding layer. Each of the successive layers includes at least two materials wherein one material is a sacrificial material and one material is a structure material. Each of the successive layers defines a successive cross-section through the three-dimensional structure. Producing each of the layers includes depositing the sacrificial material by means of an electrochemical process and depositing the structure material by means of physical gas phase deposition. After a multitude of successive layers has been produced, the three-dimensional structure is uncovered by removing at least a part of the sacrificial material. The sacrificial material is at least one of a group consisting of nickel, silver, palladium, and gold.
