Beyond Serrated Flow in Bulk Metallic Glasses: What Comes Next?

“…A sensible contribution to the question if the long-range signatures are caused by only residual internal stresses or also structural changes was recently provided via fluctuation microscopy. [70] These measurement indicated a micron-wide damage zone around the shear-band core that indeed revealed structural changes. We emphasize that this is a distinctly different observation than the signature of a long-range residual stress field.…”

Unveiling the Local Atomic Arrangements in the Shear Band Regions of Metallic Glass

“…The observations associated the contrast to density reduction [11] and cavities [12] in the SB. STEM-HAADF imaging and fluctuation electron microscopy (FEM) [10,[13][14][15][16] revealed variation of the intensity and local diffraction patterns along SBs in several types of multi-axially deformed MGs. The variations were associated with density and structural fluctuations; atom probe tomography (APT) [17] confirmed Al redistribution along SBs in a AlYFe MG, indicating that chemical modifications also occur during shear banding.…”

“…A recent FEM study indicated that there is a structural difference between the vicinity of SBs and the undeformed matrix. [14][15][16] Up to now, the explicit depiction of the atomic arrangement in the SBAZs, their nanoscale spatial distribution respect to the SBs and the structural-chemical correlation during plastic deformation are not yet known.…”

Metallic glasses

“…Good plasticity and toughness correlate with the plastic strain being accommodated by a high population density of bands with correspondingly small shear on each (Figure 3a-b). 35 Recent studies have improved our knowledge of the structure and properties of the interior of shear bands and their environment, 36,37 but to date, these studies do not offer a guide toward improved properties.…”
