| Popis: | International audience; Nanoindentation is widely used to investigate elastic modulus, hardness and work hardening behaviour of nano- and micro-scale laminates. In this work, 16 nm accumulative roll bonding (ARB) Cu/Nb nanolaminate is used as a test material due to its interfacial anisotropy owing to the presence of contrasting interfaces along rolling (RD) and transverse direction (TD). Nanoindentation was performed along TD as well as RD of ARB Cu/Nb nanolaminate, and then scanning probe microscopy (SPM) data were collected to measure the pileup along RD and TD. Nanolaminate along RD was found to show higher surface pileup than TD which is attributed to crystallographic and interfacial anisotropy resulting in (a) higher yield strength (low plasticity) along TD in comparison to RD and (b) high interfacial sliding in the case of TD resulting in less co-deformation of layers in comparison to RD. The characterization of surface pileup is of significant importance for facilitating the study of anisotropic micro/nanolaminates. |
