摘要

Abstract

BSTRACTWe used a novel diffraction-based method to extract the local

atomic-level elastic strain in nanoscale amorphous TiAl films during

in situ

transmission electron microscopy deformation

while simultaneously measuring the macroscopic strain. The complementary strain measurements revealed significant anelastic deformation

which was independently confirmed by strain rate experiments. Furthermore

the distribution of first nearest-neighbor distances became narrower during loading and permanent changes were observed in the atomic structure upon unloading

even in the absence of macroscopic plasticity. The results demonstrate the capability of

in situ

electron diffraction to probe structural rearrangements and decouple elastic and anelastic deformation in metallic glasses.
