    摘要: A palladium-copper-silver alloy consisting of 40 to 58% by weight of palladium, 25 to 42% by weight of copper, 6 to 20% by weight of silver, optionally up to 6% by weight of at least one element from the group ruthenium, rhodium, and rhenium, and up to 1% by weight of impurities, wherein the palladium-copper-silver alloy contains a crystalline phase with a B2 crystal structure and has 0% by volume to 10% by volume of precipitates of silver, palladium, and binary silver-palladium compounds. The invention also relates to a molded body, a wire, a strip, or a probe needle made of such a palladium-copper-silver alloy and to the use of such a palladium-copper-silver alloy for testing electrical contacts or for electrical contacting or for the production of a sliding contact. The invention also relates to a method for producing a palladium-copper-silver alloy.

    摘要: Platinum-nickel-based ternary or higher alloys include platinum at about 65-80 wt. %, nickel at about 18-27 wt. %, and about 2-8 wt. % of ternary or higher additions that may include one or more of Ir, Pd, Rh, Ru, Nb, Mo, Re, W, and/or Ta. These alloys are age-hardenable, provide hardness greater than 580 Knoop, ultimate tensile strength in excess of 320 ksi, and elongation to failure of at least 1.5%. The alloys may be used in static and moveable electrical contact and probe applications. The alloys may also be used in medical devices.

    摘要: Systems and methods disclosed herein relate to the manufacture of metallic material with a thermal expansion coefficient in a predetermined range, comprising: deforming, a metallic material comprising a first phase and a first thermal expansion coefficient. In response to the deformation, at least some of the first phase is transformed into a second phase, wherein the second phase comprises martensite, and orienting the metallic material in at least one predetermined orientation, wherein the metallic material, subsequent to deformation, comprises a second thermal expansion coefficient, wherein the second thermal expansion coefficient is within a predetermined range, and wherein the thermal expansion is in at least one predetermined direction. In some embodiments, the metallic material comprises the second phase and is thermo-mechanically deformed to orient the grains in at least one direction.
