Title: Microstructure evolution during near- $T_{g}$ annealing and its effect on shear banding in model alloys

Abstract

By performing extensive molecular dynamics simulations, we investigate herein the deformation behavior in $A l_{90} S m_{10}$ and $C u_{64.5} Z r_{35.5}$ alloys after elongated isothermal annealing in the vicinity of the glass-transition temperature ( $T_{g}$ ). Different microstructural response to the annealing process was observed: $A l_{90} S m_{10}$ maintains the glassy structure with improved energetic stability, enhanced short-range order (SRO), and a more pronounced spatial network that extends beyond the first atomic shell, while $C u_{64.5} Z r_{35.5}$ forms nanocrystalline Laves $C u_{2} Zr$ phases. Shear banding occurs in both annealed systems under shear loading. For $A l_{90} S m_{10}$ , the spatial network formed by the local clusters characterizing the SRO of the system is significantly weakened but remains appreciable in the shear band. In contrast, the crystalline ordering in the $C u_{64.5} Z r_{35.5}$ is completely destroyed during shear banding. Consequently, while displaying higher yield strength, the annealed $C u_{64.5} Z r_{35.5}$ sample appears to be less ductile. By carefully examining the effect of microstructures on the structural ordering in the shear band and the consequent mechanical response, our work contributes to a better understanding of the deformation mechanism of amorphous alloys as compared with that in crystalline materials.
