Abstract

The amorphous/amorphous nanolaminates(A/ANLs)have aroused great attentions owing to their tunable structure and enhanced mechanical properties.However,the plastic deformation mechanism of A/ANLs have yet been clarified.Here,we systematically examined the mechanical properties and deformation behavior of series of NiNb/ZrCuNiAl A/ANLs via nanoindentaion test.It was found that both the amount and morphology of amorphous/amorphous interface(A/AIs)played crucial roles in the plastic deforma-tion of A/ANLs.Less and straighter A/AIs facilitated multiple shear banding deformation,of which the hardness increased with decreasing layer thickness,as the A/Als hindered the propagation of shear bands(SBs).Whilst,more and wavier A/AIs promoted homogeneous deformation,of which the hardness stayed at a much lower value and was relatively irrelevant with the layer thickness,for the promoted activa-tion of shear transformation zones by A/Als.Our results provide guidance for modifying the mechanical properties of amorphous alloys with interface engineering design.
