Preparation and tensile properties of amorphous Fe78Si9B13/nano-Ni laminated composite

Amorphous Fe78Si9B13/nano-Ni laminated composite was prepared by electrodeposition method. The tensile properties of laminated composite at room temperature were examined. The laminated composite exhibits a very high tensile strength and reasonable tensile elongation. This is attributed to a good bonding between amorphous Fe78Si9B13 layer and nano-Ni layers. The amorphous layer can deform in conformity with Ni layers and be significantly stretched without fracture. The apparent surface energy γf of amorphous Fe78Si9B13 ribbon in the laminated composite is 7 times larger than γf of amorphous ribbon in monolithic form. The isostrain model may be insufficient to explain the tensile behavior of the laminated composite.
