ALLOY WITH SELECTED ELECTRICAL CONDUCTIVITY AND ATOMIC DISORDER, PROCESS FOR MAKING AND USING SAME

摘要

A primary alloy includes: nickel; copper; zinc; an electrical conductivity from 5.2% International Annealed Copper Standard (IACS) to 5.6% IACS measured in accordance with ASTM E1004-09 (2009); and a disordered crystalline phase wherein atoms of the nickel, cooper, and zinc are randomly arranged in the disordered crystalline phase at room temperature in a post-annealed state. A process for making the primary alloy includes heating a secondary alloy to a first temperature that is greater than or equal to an annealing temperature to form an annealing alloy, the secondary alloy including a secondary phase; and quenching, by cooling the annealing alloy from the first temperature to a second temperature that is less than the annealing temperature, under a condition effective to form the primary alloy including the disordered crystalline phase, wherein the disordered crystalline phase is different than the secondary phase of the secondary alloy.
