It is proposed to use the atom probe tomography characterization to achieving a detailed knowledge on the chemical and the structural variation in Shear bands and compare these results with the parent bulk metallic glass. This is achieved by analyzing the density fluctuation and short-to-medium-range order in selected systems. Atomic transport along the shear band is also measured. The significant, by orders of magnitude, enhancement of the diffusion rate with respect to that in the surrounding matrix suggests that the shear bands represent short-circuit diffusion paths. Our findings will provide a reliable chemical/structural study, which may help us to understand the nature, and properties of metallic glasses.
