✦ Synopsis

The tensile behavior of the monolithic ZrCu thin film metallic glass and the ZrCu/Cu multilayer coating on pure Cu foil is systematically examined. The extracted tensile modulus and strength of the 1 m films are in good agreement with the theoretical rule of mixture prediction. The extracted 2 m film data are lower, but can be corrected back by considering the actual intact cross-sectional area during the tensile loading. The current results reveal that the ZrCu/Cu multilayer coating exhibit much better tensile performance than the monolithic ZrCu coating despite of the brittle deformation. To obtain ductile amorphous/crystalline multilayer coating, two principles are suggested in this paper.
