The structural behaviour of Cu 50 Zr 50 and Cu 65 Zr 35 metallic glasses under uniaxial tensile stress was investigated in situ by high-energy X-ray synchrotron diffraction. The components of the elastic strain tensor were determined from both the change of positions of first maximum of the structure factor in reciprocal space as well as from the maxima of the atomic pair correlation function in real space. The atomic scale strain agrees with the macroscopic strain values. The topological and chemical short-range order of the Cu-Zr glasses changes upon loading. The number density of Cu-Zr and Zr-Zr nearest neighbour atomic pair becomes oriented along the loading direction whereas the partial nearest neighbour distances are only weakly influenced.

## a b s t r a c t Zr-based bulk-metallic glasses (BMGs) are being studied widely because Zr-based BMGs exhibit good glass-forming abilities and excellent properties, such as material strengths. In the current paper, the fatigue behaviors of Zr 50 Cu 40Àx Al 10 Pd x [x: 0-7 atomic percent (at.%)]
Experiments were conducted on bulk metallic glasses (BMGs) to identify a crucial factor that governs the degree of the plasticity shown by these alloys. It was found that in situ formation of nanocrystallites, which is known as the deformation-induced nanocrystallization, play a key role in providin
