We report a stable fracture phenomenon during the compression of a malleable Zr-based bulk metallic glass. In the process; the shear band along which the sample fails is constrained by the machine crosshead; thus causing a slow release of the stress and the elastic energy by small steps in the stress-strain curve. A novel and unique fishbone-like pattern was observed on the fracture surface after the final rupture instead of the typical vein-like pattern usually found upon catastrophic failure for metallic glasses. The formation of this pattern might be a result of the modest temperature rise during failure and the frustration of the meniscus instability in the crack tip due to stress redistribution in the constraint. This fracture behavior; where the crack propagation is at a much lower speed and the elastic energy is released in a stable way; might be suitable for studying the crack propagation process and the fracture mechanism in metallic glasses. © 2012 American Institute of Physics;
