ABSTRACT:
Zirconium-titanium alloys containing at least one of the transition metal elements of iron, cobalt, nickel and copper are disclosed. The alloys consist essentially of about 1 to 64 atom percent titanium plus at least one element selected from the group consisting of about 15 to 27 atom percent iron, about 15 to 43 atom percent cobalt, about 15 to 42 atom percent nickel and about 35 to 68 atom percent copper, balance essentially zirconium plus incidental impurities, with the proviso that when the iron is present, the maximum amount of titanium is about 25 atom percent, when cobalt is present, the maximum amount of titanium is about 54 atom percent and when nickel is present, the maximum amount of titanium is about 60 atom percent. The alloys in polycrystalline form are capable of being melted and rapidly quenched to the glassy state. Substantially totally glassy alloys of the invention evidence unusually high electrical resistivities of over 200 .mu..OMEGA.-cm.
