摘要

BSTRACTPlastic deformation and fracture behavior of Cu/V nanoscale metallic multilayers (NMMs) were systematically investigated through

in situ

transmission electron microscopy testing. Two different types of interfaces: sharp interfaces and interfacial transition zones (ITZs)

formed in the as-fabricated Cu/V NMMs. Upon deformation

sharp interfaces

and ITZs exert distinct influences on the fracture behavior of Cu/V NMMs. Sharp interfaces can impede the crack propagation by deflecting the crack propagation and blunting the crack tip

while the ITZs can induce microcracks and facilitate the fracture process. These findings shed light on the important roles of interface structures in the deformation of a broad class of NMMs.
