Abstract
Abstract A method of laminating first and second metal sheets to one another, comprises the steps of superposing the metal sheets and including therebetween a layer of amorphous metal and laminating the sheets to one another. During the lamination a pressure is applied by cold rolling for bonding the first and second sheets together.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
71 words
A method of laminating first and second metal sheets to one another, comprising the following steps: (a) superposing said first and second metal sheets and including therebetween a layer of amorphous metal and (b) subsequent to step (a) bonding to one another, by cold rolling, said first and second sheets, whereby said first and second sheets are laminated to one another while the amorphous metal is maintained in the amorphous state.
Claim 2
Independent Claim
71 words
A method of laminating first and second metal sheets to one another, comprising the following steps: (a) superposing said first and second metal sheets and including therebetween a layer of amorphous metal and (b) subsequent to step (a) bonding to one another, by cold rolling, said first and second sheets, whereby said first and second sheets are laminated to one another while the amorphous metal is maintained in the amorphous state.
Claim 3
Dependent Claim
22 words
A method as defined in claim 1, wherein the thickness of said layer of amorphous metal is between 10 and 50 μm.
Claim 4
Dependent Claim
42 words
A method as defined in claim 1, wherein the step of including said layer of amorphous metal comprises the step of positioning between said first and second sheets said layer having a width substantially equalling that of said first and second sheets.
Claim 5
Dependent Claim
37 words
A method as defined in claim 1, wherein the step of including said layer of amorphous metal comprises the step of positioning between said first and second sheets said layer in strips in a side-by-side, spaced arrangement.
Claim 6
Dependent Claim
30 words
A method as defined in claim 1, including the step of reducing the overall thickness of said first and second sheets and said amorphous metal layer by 40 to 80%.
Claim 7
Dependent Claim
36 words
A method as defined in claim 1, wherein the step of cold rolling includes the step of reducing the overall thickness of said first and second sheets and said amorphous metal layer by 40 to 80%.
Claim 8
Dependent Claim
33 words
A method as defined in claim 1, further comprising the step of providing, prior to the superposing step, a surface of at least one of said sheets with said layer of amorphous metal.
Claim 9
Dependent Claim
41 words
A method as defined in claim 7, wherein the step of providing the surface of at least one of said sheets with said layer of amorphous metal comprises the step of irradiating said at least one sheet with a laser beam.

Claim 13
Dependent Claim
93 words
A laminate product comprising first and second metal sheets being in a superposed relationship and a layer of amorphous metal positioned between said first and second sheets, said product being obtained by a process comprising the following steps: (a) superposing said first and second metal sheets and including therebetween a layer of amorphous metal and (b) subsequent to step (a) bonding to one another, by cold rolling, said first and second sheets, whereby said first and second sheets are laminated to one another while the amorphous metal is maintained in the amorphous state.
Claim 14
Dependent Claim
93 words
A laminate product comprising first and second metal sheets being in a superposed relationship and a layer of amorphous metal positioned between said first and second sheets, said product being obtained by a process comprising the following steps: (a) superposing said first and second metal sheets and including therebetween a layer of amorphous metal and (b) subsequent to step (a) bonding to one another, by cold rolling, said first and second sheets, whereby said first and second sheets are laminated to one another while the amorphous metal is maintained in the amorphous state.
