| 英文摘要 | We report a novel plastic deformation mechanism of bulk metallic glass composites (BMGCs) containing metastable beta-Ti dendrites. Plastic deformation of the BMGCs beyond the ultimate tensile strength is mediated by cooperative shear events, which comprise a shear band in the glassy matrix and a continuous omega-Ti band with a thickness of similar to 10 nm in the beta-Ti dendrite. The cooperative shear leads to serrated shear avalanches. The formation of narrow omega-Ti bands is caused by high local strain rates during the cooperative shear. The cooperative shear mechanism enriches the deformation mechanisms of BMGCs and also deepens the understanding of omega-Ti formation. |
