Bulk metallic glasses (BMGs) have attracted considerable attention in the last few decades particularly triggered by their potential applications as novel structural and/or functional materials, owing to their su-perior strength, large elastic strain limit and relatively low Young′s modulus etc.compared to their crys-talline counterparts.Here, a 3D reconstruction application to the fractography and the morphology of shear bands was reported for a ductile Zr56 Co28 Al16 (at.%) BMG through a Phenom series desktop scan-ning electron microscope.The results of the 3D reconstruction and the following contour analysis indicate a typical shear fracture mode for the investigated alloy.It is inferred that the fractography and the morphology of shear bands might be dependent on their composition, structure states, and loading conditions for BMGs.
