摘要: A conductive element of a cable or a wire is formed of an improved aluminum-zirconium alloy. The aluminum-zirconium alloy further includes an inoculant. The aluminum-zirconium alloy exhibits excellent ultimate tensile strength values and resistance to heat. Bonding wires formed from an improved aluminum-zirconium alloy exhibiting certain ultimate tensile strength values, fatigue resistance and/or creep rates are also described. Methods of forming cables and wires are also further disclosed.

摘要: Aluminum-zirconium and aluminum-zirconium-lanthanide superalloys are described that can be used in high temperature, high stress and a variety of other applications. The lanthanide is preferably holmium, erbium, thulium or ytterbium, most preferably erbium. Also, methods of making the aforementioned alloys are disclosed. The superalloys, which have commercially-suitable hardness at temperatures above about 220° C., include nanoscale Al3Zr precipitates and optionally nanoscale Al3Er precipitates and nanoscale Al3(Zr,Er) precipitates that create a high-strength alloy capable of withstanding intense heat conditions. These nanoscale precipitates have a L12-structure in α-Al(f.c.c.) matrix, an average diameter of less than about 20 nanometers (“nm”), preferably less than about 10 nm, and more preferably about 4-6 nm and a high number density, which for example, is larger than about 1021 m−3, of the nanoscale precipitates. The formation of the high number density of nanoscale precipitates is thought to be due to the addition of inoculant, such as a Group 3A, 4A, and 5A metal or metalloid. Additionally, methods for increasing the diffusivity of Zr in Al are disclosed.
