abstract = {Bulk metallic glasses (BMG) are very attractive materials
exhibiting high specific strength, decent corrosion
resistance and other benefiting features due to their
amorphous microstructure. However, the mechanisms of
mechanical properties as an issue of structure-properties
relation in BMGs are not understood as well as those in
polycrystalline materials. For example, the driving force
for fatigue in crystalline materials is connected to grain
boundary slip and the formation of dislocations i.e. to
those structural elements whose existence in BMGs is still
debatable. In order to find a link between the mechanical
properties and the microstructure in BMG, researchers
investigate structural heterogeneities i.e. clusters. The
size order of the clusters and intercluster boundaries are
within the resolution of small-angle neutron scattering
(SANS) techniques. Here we present the results of SANS and
very-small-angle neutron scattering (VSANS) studies of
Zr46.75Ti8.25Cu7.5Ni10Be27.5 bulk metallic glass after
deformation with and without ultrasonic vibrations. VSANS
measurements revealed the creation and growth of large
micropores induced by ultrasonic vibration.},
