A method for making small diameter NiTi metal alloy components, including balls, comprising providing a metal powder comprising nickel, titanium, and a transition metal, consolidating the metal powder into cylindrical rods, and cutting the cylindrical rods into segments. The segments are then machined into spheres slightly larger than the finished ball size diameter. The spheres are heat treated to solutionize and dissolve all phases and subsequently cooled without the need for rapid quenching due to the influence of the transition metal to suppresses the formation of soft phases in the spheres, wherein such soft phases prevent hardening, to achieve a Rockwell hardness of HRC 58-62. Finally, the hardened spheres are polished until the desired finished ball size diameter and surface finish is achieved.

A nickel alloy sputtering target comprises: a nickel alloy containing an element capable of decreasing the Curie temperature of nickel, wherein an area ratio of a Ni phase having a Ni content of 99.0 mass % or more is 13% or less and an average crystal grain diameter is 100 gm or less. It is preferred that an area ratio of a high-purity Ni phase having a Ni content of 99.5 mass % or more be 5% or less.

Ni—Mn—Si based braze filler alloys or metals which may be nickel-rich, manganese-rich, or silicon-rich braze filler alloys, have unexpectedly narrow melting temperature ranges, low solidus and low liquidus temperatures, as determined by Differential Scanning calorimetry (DSC), while exhibiting good wetting, and spreading, without deleterious significant boride formation into the base metal, and can be brazed at lower temperatures. The nickel rich alloys contain 58 wt % to 70 wt % nickel, the manganese-rich alloys contain 55 wt % to 62 wt % manganese, and the silicon-rich alloys contain 25 wt % to 29 wt % silicon. Copper with or without boron to partly replace nickel may be employed without any substantial increase of the melting point, or to reduce the melting point. The braze filler alloys have sufficient brazability to withstand high temperature conditions for thin-walled aeronautical and other heat exchangers.

Multi-layer metal or pseudometallic materials having engineered anisotropy are disclosed. The multi-layer materials having defined engineered grain orientations in each layer of the multi-layer material and bond layers between adjacent layers orthogonal to the grain orientations. This configuration distributes applied stress across the plurality of layers in the multi-layer metal material and around a neutral axis of the multi-layer metal material and increases the overall mechanical properties of the disclosed multi-layer metal material relative to conventional wrought metal materials of the same or similar chemical constitution. The microstructure of each layer, group of layers, or across multiple layers may be tailored to the intended application of a device made from the material. Individual layers may be tuned for property variations, such as gradients, or to adjust the bond layer characteristics. A method of making the multi-layer metal materials by physical vapor deposition to deposit each layer as crystalline grain structures and allow for layer-by-layer control over the physical, mechanical and chemical properties of each layer in the multi-layer metal as well as a bond layer between adjacent layers is disclosed.
