Abstract

Novel metal alloy compositions which are obtained in the amorphous state and are superior to such previously known alloys based on the same metals are provided; these new compositions are easily quenched to the amorphous state and possess desirable physical properties. Also disclosed is a novel article of manufacture in the form of wire of these novel amorphous metal alloys and of other compositions of the same type.

Claims

1. A METAL ALLOY OF THE FORMULA MAYBZC WHICH IS AT LEAST 50 PERCENT AMORPHOUS AND WHEREIN M IS A METAL SELECTED FROM THE GROUP CONSISTING ESSENTIALLY OF IRON, NICKEL, CHROMIUM, COBALT, OR VANADIUM OR A MIXTURE THEREOF, Y IS A METALLOID SELECTED FROM THE GROUP CONSISTING OF PHOSPHORUS, CARBON AND THE GROUP CONSISTING OF ALUMINUM, SILICON, TIN, ANTIMONY, GER BORAN OR A MIXTURE THEREOF, AND Z IS AN ELEMENT SELECTED FROM THE GROUP CONSISTING OF ALUMINUM, SILICON, TIN, ANTIMONY, GERMANIUM, INDIUM, AND BERYLLIUM AND MIXTURES THEREOF, "A", "b" AND "C" ARE AUTOMIC PERCENTAGES RANGING FROM ABOUT 60 TO 90, 10 TO 30 AND 0.1 TO 15 RESPECTIVELY WITH THE PROVISO THAT A PLUS B PLUS C EQUALS 100.

2. The amorphous metal alloy of claim 1 wherein '"'"''"'"''"'"''"'"'a,'"'"''"'"''"'"''"'"' '"'"''"'"''"'"''"'"'b'"'"''"'"''"'"''"'"' and '"'"''"'"''"'"''"'"'c'"'"''"'"''"'"''"'"' range from 69 to 84.5, 15 to 25, and 0.5 to 6, respectively.

3. The amorphous metal alloy of claim 1 wherein up to about one-fourth of the metal M is replaced by elements commonly alloyed with iron or nickel.

4. As an article of manufacture, sheets,ribbons and powders of the amorphous metals having the compositions of claim 1.

5. As an article of manufacture, sheets, ribbons and powders of the amorphous metals having the compositions of claim 3.

6. As an article of manufacture, a metal wire comprising an alloy which is at least 50 percent amorphous and having a composition of the formula TiXj wherein T is a transition metal or mixture of said transition metals and X is an element selected from the group consisting of aluminum, antimony, beryllium, boron, germanium, carbon, indium, phosphorus, silicon, tin, and mixtures thereof and wherein i and j are in atomic percentages and range from about 70 to about 87 and from about 13 to about 30 respectively.

7. The article of claim 6 wherein i ranges from about 74 to about 84 and j ranges from about 16 to about 26.

8. Amorphous metal wire of claim 6 wherein iron comprises at least 60 atomic percent of T.
