Abstract: A powder for the production of a superconducting component. The powder includes NbxSny, where 1?x?6 and 1?y?5, and three-dimensional agglomerates having a particle size D90 of less than 400 ?m, as determined via a laser light scattering. The three-dimensional agglomerates have primary particles which have an average particle diameter of less than 15 ?m, as determined via a scanning electron microscopy, and pores of which at least 90% have a diameter of from 0.1 to 20 ?m, as determined via a mercury porosimetry.

Abstract: A three-dimensional article is obtained by a process which includes providing a metal powder, and using the metal powder to build up the three-dimensional article layer by layer. The metal powder is a metal which is selected from the group of tantalum and impurities, titanium and impurities, niobium and impurities, an alloy of tantalum, niobium and impurities, an alloy of titanium, niobium and impurities, and an alloy of tantalum, titanium, niobium and impurities. Particles of the metal powder have a dendritic microstructure. Particles of the metal powder have an average aspect ratio TA of from 0.7 to 1, where ?A=xFeret min/xFeret max.

Abstract: A device, a method and a computer program product for machining a workpiece, in particular for cutting teeth into a workpiece, includes a base, a workpiece spindle mounted rotatably about a first axis (A) for receiving the workpiece, a first machining head having a first tool spindle mounted rotatably relative to a first tool axis for receiving a first machining tool, and a second machining head having a second tool spindle mounted rotatably relative to a second tool axis for receiving a second machining tool. At least the first machining head is provided with the first machining tool for power skiving the workpiece and at least the second machining head is variably positionable and/or variably orientable relative to the first machining head and independently of the first machining head.
