| 英文摘要 | The dilatancy signatures associated with the plastic deformation of a typical Zr-based amorphous alloy are captured by using synchrotron radiation X-ray diffraction (XRD) and small angle X-ray scattering (SAXS) techniques. XRD demonstrates that the right-subpeak atoms of the second coordination shell accommodate the local dilatation, which occurs prior to the plastic yielding and during the softening-to-flow transition process. Mediated by the local dilatation, local atomic rearrangements can operate at the left-subpeak of the second shell and/or at the fourth shell with a characteristic lengthscale of about 1 nm. The obtained dilatancy signatures of amorphous plasticity are further confirmed by SAXS in terms of the nano-scale structural heterogeneity. |
