High temperature deformation behavior of amorphous Fe78Si9B13/nano-Ni laminated composite
AbstractThe high temperature deformation behavior of amorphous Fe78Si9B13/nano-Ni laminated composite prepared by pulse electrodeposition method was investigated under uniaxial tension and gas pressure forming. The microstructures of the specimens were studied by means of SEM and TEM. The laminated composite demonstrates good deformation ability at high temperature. A maximum elongation of 115.5% was obtained at 450°C and an initial strain rate of 8.33×10−4s−1, which is much larger than that of monolithic amorphous Fe78Si9B13 ribbon (36.3%) tested under the same experimental conditions. Amorphous layer is constrained by good interfacial bonding to deform in conformity with nano-Ni layers and can be significantly stretched without fracture. In the gas pressure forming experiments, the relative bulging height (RBH) reaches 0.4 due to the limit of the equipment supplied gas pressure.
