dc.description.abstractGlass transition temperature and plastic yield strength are known to be correlated in metallic glasses. We have observed by in-situ synchrotron high energy X-ray diffraction anisotropy in the thermal expansion behavior of the nearest neighbor and second nearest neighbor atomic distances in the building blocks of Zr-Cu-Ni-Al based bulk metallic glass, leading inevitably to local shear stresses. Mechanical yielding of the latter on the atomic scale leads to the glass transition and the increase of the free volume. These experimental results uncover the mechanism, how glass transition and yield strength are linked.en_AU
