Anisotropy in mechanical properties during microscale uniaxial tensile deformation of Cu/Ni clad foils

摘要

The anisotropy in the mechanical properties of Cu/Ni clad foils with a thickness of 100 rim under different annealing temperatures and initial specimen orientations is investigated using both uniaxial tensile tests and finite element simulations. The anisotropy is manifest by increases in the grain size and interface layer thickness. The anisotropy in the mechanical properties results from the wavy interface layer morphology and interface constraints, as microstructure coarsening makes the anisotropy apparent.
