Monolithic bulk metallic glasses (BMG) are known to have high strengths and hardness; however, they are inherently brittle, making them undesirable for structural applications wherein plastic deformation must be supported. Laminar nano-composites of BMG and other ductile metals fabricated by deposition methods allow extraordinary mechanical performances including high ductility and strength, and unique dislocation activity in the amorphous/crystalline interface; however, are limited to small sizes and in their scalability potential. Here, we report on scalable fabrication of laminar Zr-based BMG/Ni nano-composites using warm roll bonding. The influence of roll bonding processing parameter selection on the laminate morphology and microstructural evolution of the composite, along with the mechanical response at different layer thicknesses will be discussed. These probes will be correlated through studies of the fundamental defect interactions at the BMG/metal interfaces.
