摘要: Abstract Electropulsing treatment (EPT) is utilized to increase the plasticity of nanocrystalline Ni foil. Uniaxial tensile tests at room temperature are adopted investigate influence EPT on mechanical properties under different peak current density. It shown that electropulsing with certain strength can improve elongation significantly. The evolution fracture morphology, stacking faults, twinning and dislocation studied via scanning electron microscopy (SEM) transmission (TEM), plastic deformation mechanism also researched.
