A bar of noble metal or an alloy containing noble metal having a mass mB is subdivided into nm miniature bars 2, 3 each having a specified mass mk, wherein n and m each denote an integer 2, there being an interconnection of solid material (8) between directly adjacent miniature bars (2, 3). Another bar is affixed to a backing (13), to which the miniature bars are releasably attached. A method for the production of the bar consists in dividing up the same while leaving an interconnection of solid material or producing an arrangement thereof on a backing.

The invention includes a copper-nickel-zinc alloy with the following composition in weight %: Cu 47.0 to 49.0%, Ni 8.0 to 10.0%, Mn 0.2 to 0.6%, Si 0.05 to 0.4%, Pb 1.0 to 1.5%, Fe and/or Co up to 0.8%, the rest being Zn and unavoidable impurities, wherein the total of the Fe content and double the Co content is at least 0.1 weight % and wherein mixing silicides containing nickel, iron and manganese and/or containing nickel, cobalt and manganese are stored as spherical or ellipsoidal particles in a structure consisting of an - and -phase. The invention further relates to a method for producing semi-finished products from a copper-nickel-zinc alloy.

There is provided a training system capable of performing work. The system has a shape memory alloy (SMA) actuator exhibiting a generally planar transformational behavior. The system further has one or more heating elements for transforming the SMA actuator from an original shape to a trained shape, thereby performing work.

The disclosure relates to the technical field of preparing the metal material of magnesium alloy, and particularly provides a method for preparing biomedical magnesium alloy wires. The magnesium, zinc, and neodymium alloys are subject to smelting, casting, rolling, and other processes to prepare plates. The plates are subjected to a special mechanical stirring process to prepare a processing zone with the same thickness as the plates. After machining, the processing zone is used as the final product of the wire or drawn in multiple passes to finally form the wire with the required diameter. By introducing rolling and mechanical stirring processes, the disclosure improves the forming property of the wire, so that the alloy grains are significantly refined, the size of the second phase is greatly reduced and most of them are solid-soluble in the matrix, the strength of the obtained wire, and especially the elongation, is greatly improved, and better corrosion resistance is obtained, which meet the performance requirements of medical magnesium alloy wire.

There is provided a method of training a shape memory alloy (SMA) workpiece. The method includes applying a force couple to a shape memory alloy (SMA) workpiece to impart a generally planar transformational behavior to the SMA workpiece to obtain a trained shape memory alloy (SMA) workpiece.
