FIG. 1.

Compressive nominal stress-strain curves of the as-cast BMG. Inset shows a two-dimensional diffraction pattern of the BMG without applied stress.

FIG. 2.

Isotropic component, , and anisotropic component, , of the structure factor at different stresses. Inset shows the strain values measured from four maxima shifting in the structure factor at different stresses in the loading direction.

FIG. 3.

Results from the PDF analysis: (a) Isotropic component, , and anisotropic component, , of the pair correlation function. (b) Changes in the first maximum of atomic density, , at 1870 MPa in the loading direction. Inset shows deconvolution of the first nearest-neighbor shell into two Gaussians for the BMG compressed at 267 MPa in the loading direction. (c) Coordination numbers for the Cu–(Zr,Cu) and Zr–Zr atomic pairs as functions of the applied stress. (d) Strain values vs applied stress of the BMG measured from the first maximum in the PDF and from the values.
