AbstractTensile properties of ultrafine grained Cu/Ni laminated composites prepared by dual-bath electrodepositon technique were investigated by tensile tests at different strain rates ranging from 1 x 10(-5) to 1 x 10(-2) s(-1). The results show that the stress gradient close to heterogeneous interfaces established at high strain rates may influence mechanical properties of the ultrafine-grained Cu/Ni laminates, leading to a simultaneous increase in strength and ductility as the strain rate increases from 1 x 10(-5) to 1 x 10(-2) s(-1). The effect of such stress gradient in the laminated composites is analyzed to understand the abnormal increase in ductility with strain rate. (C) 2014 Elsevier B.V. All rights reserved.
