Plastic Deformation Development Inside Flawed NI35AL28CO37 Metallic Glass Thin Film under Tensile Simulation

Abstract
Metallic glasses (MGs) have received extensive attention due to their great attractive mechanical properties. However, the correlation between deformation development and the square flaw is lack of investigation. In this study, the effects of flaw shape on the mechanical strength and deformation development of Ni35Al28Co37MGs are investigated via molecular dynamics simulation under tension test. We find that the ultimate tensile strength values are almost unchanged at strain rates in the range from 108 to 109 s-1, while they sharplyrise up at a strain rate of 5 × 109 s-1. The shear strain grows perpendicular to the tensile direction and increases gradually with the strain. Besides, the failure strength and the deformation in the Ni35Al28Co37MGs depend on critical stress concentration position.
