Abstract
Abstract Glassy metal alloys of compositions in the Be-Ti-Zr system suitable as temperature sensing elements for resistance thermometers are provided. The compositions consist essentially of about 20 to 45 atom percent beryllium, about 2 to 80 atom percent zirconium, 0 to about 2 atom percent of at least one metal of vanadium, chromium, manganese, iron, nickel and cobalt, and the balance essentially titanium and incidental impurities. The alloys of the invention combine a high temperature coefficient of resistance and negligible temperature-dependent magneto-resistance.
