Abstract
Abstract Amorphous metal alloy shapes are synthesized by providing an intimate mixture of the components of the amorphous alloy, which mixture includes at least one ductile component. The mixture may be subjected to well-known forming techniques at a temperature below the crystallization temperature of the amorphous metal alloy to be formed. The ductile component of the mixture acts as a binder matrix to provide strength and uniform properties to the formed object.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
71 words
A process for the production of substantially amorphous metal alloy objects comprising: (a) preparing an intimate mixture of the components of the amorphous metal alloy by a solid state reaction, at least one component of the intimate mixture being a ductile component; and (b) forming the intimate mixture into an object at a temperature below the crystallization temperature of the metal alloy so as to form an amorphous metal alloy object.
Claim 2
Dependent Claim
71 words
A process for the production of substantially amorphous metal alloy objects comprising: (a) preparing an intimate mixture of the components of the amorphous metal alloy by a solid state reaction, at least one component of the intimate mixture being a ductile component; and (b) forming the intimate mixture into an object at a temperature below the crystallization temperature of the metal alloy so as to form an amorphous metal alloy object.
Claim 3
Dependent Claim
27 words
The process in accordance with claim 1 wherein said intimate mixture comprises particles having a maximum particle size of from about 10 Angstroms to about 1000 Angstroms.
Claim 4
Dependent Claim
27 words
The process in accordance with claim 1 wherein said intimate mixture comprises particles having a maximum particle size of from about 10 Angstroms to about 500 Angstroms.
Claim 5
Dependent Claim
26 words

Claim 7
Dependent Claim
37 words
The process in accordance with claim 1 wherein said ductile component comprises from about 10 atomic percent to about 95 atomic percent of the amorphous metal alloy based on the total composition of the amorphous metal alloy.
Claim 8
Dependent Claim
35 words
The process in accordance with claim 1 wherein step (b) comprises the step of forming the intimate mixture into an object followed by heat treating the so-formed object so as to induce the amorphous state.
