Abstract
Continuous filaments of zirconium-copper glassy alloys containing at least one of the transition metal elements of iron, cobalt and nickel are disclosed. The filaments are substantially totally glassy and have a composition consisting essentially of about 1 to 68 atom percent copper plus at least one element selected from the group consisting of about 1 to 29 atom percent iron, about 1 to 43 atom percent cobalt and about 1 to 42 atom percent nickel, balance essentially zirconium plus incidental impurities. The glassy alloy filaments of the invention evidence unusually high electrical resistivities of over 200 .mu..OMEGA.-cm.
Claims3
Substantially continuous filaments of a substantially glassy zirconium-copper alloy containing an element selected from the group consisting of cobalt and nickel, said alloy consisting essentially of a composition selected from the group consisting of:
- (a) zirconium, copper and cobalt which, when plotted on a ternary composition diagram in atom percent Zr, atom percent Cu and atom percent Co, is represented by a polygon having at its corners the points defined by:
- (1) 64 Zr - 35 Cu - 1 Co
- (2) 31 Zr - 68 Cu - 1 Co
- (3) 35 Zr - 35 Cu - 30 Co
- (4) 56 Zr - 1 Cu - 43 Co
- (5) 64 Zr - 1 Cu - 35 Co;
- and
- (b) zirconium, copper and nickel which, when plotted on a ternary composition diagram in atom percent Zr, atom percent Cu and atom percent Ni, is represented by a polygon having at its corners the points defined by:
- (1) 64 Zr - 35 Cu - 1 Ni
- (2) 31 Zr - 68 Cu - 1 Ni
- (3) 40 Zr - 28 Cu - 32 Ni
- (4) 57 Zr - 1 Cu - 42 Ni
- (5) 71 Zr - 1 Cu - 28 Ni.
