    Abstract

    In order to produce thin gauge bulk metallic glass (BMG) sheets, thick Zr-based BMG plates were sandwiched between upper and lower outer copper sheets and then warm-rolled jointly in the supercooled liquid region. Proper control of the outer sheet thickness during sandwich rolling provided successful rolling of the BMG sheets. The finite element method simulation disclosed that sandwich rolling with thick outer sheets minimized the shear strains leading to a strain state close to the plane strain in the rolled BMG sample.
