Abstract

Ultrasonic consolidation is a novel forming process for fabricating laminated composites with alternate stacking of tough layer and stiff layer to achieve the desired properties. Laminate composites stacking with Al foil and Fe-based amorphous strip were produced by ultrasonic consolidation. X-ray diffraction and microhardness measurements indicated that the respective structure of the individual layers was preserved together with excellent hardness and stiffness of the amorphous layer. Shear bands in the amorphous strip combined with thermodynamic stability measurements by differential scanning calorimeter (DSC) indicated that the plastic deformation of amorphous layer led to coordinated deformation and mechanical bonding during the ultrasonic consolidation process.
