Abstract
Abstract Amorphous uranium-base alloys are disclosed having the general formula UxCryVz, where x ranges from about 60 to 80 atom percent and y and z each range from about 0 to 40 atom percent, with the total of y and z ranging from about 20 to 40 atom percent. These amorphous alloys exhibit high strength and good creep resistance, and are thermally stable up to about 500 DEG C.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
48 words
A uranium base metal alloy which is at least 50 percent amorphous comprising about 60 to 80 atom percent of uranium and about 20 to 40 atom percent of chromium and/or vanadium, and a maximum of about 10 atom percent of other alloying elements replacing chromium and/or vanadium.
Claim 2
Dependent Claim
48 words
A uranium base metal alloy which is at least 50 percent amorphous comprising about 60 to 80 atom percent of uranium and about 20 to 40 atom percent of chromium and/or vanadium, and a maximum of about 10 atom percent of other alloying elements replacing chromium and/or vanadium.
Claim 3
Dependent Claim
59 words
The alloy of claim 1 in which the alloy consists essentially of the composition U x Cr y V z , where x ranges from about 60 to 80 atom percent and y and z each range from 0 to about 40 atom percent, with the total of y and z ranging from about 20 to 40 atom percent.
Claim 4
Dependent Claim
39 words

Claim 5
Dependent Claim
39 words
The alloy of claim 2 in which the alloy consists essentially of the composition U x V z , where x ranges from about 60 to 80 atom percent and z ranges from about 20 to 40 atom percent.
