Environmental transmission electron microscopy study of hydrogen charging effect on a Cu-Zr metallic glass
Hydrogen induced plasticity has been found in metallic glasses; however, the underlying mechanism remains unclear. Herein, we studied a Cu-Zr metallic glass charged in a hydrogen atmosphere inside an environmental transmission electron microscope. Compression tests of hydrogen charged nanopillars sh...

| description | Hydrogen induced plasticity has been found in metallic glasses; however, the underlying mechanism remains unclear. Herein, we studied a Cu-Zr metallic glass charged in a hydrogen atmosphere inside an environmental transmission electron microscope. Compression tests of hydrogen charged nanopillars show more controllable deformation compared to uncharged ones. A variable resolution fluctuation electron microscopy study of the hydrogen charged samples reveals an increase in the correlation length of the medium-range order. Our results provide experimental evidence for hydrogen-induced heterogeneity and support the idea that increasing the degree of heterogeneity leads to multiple local shear events and suppresses catastrophic shear banding. IMPACT STATEMENT Direct evidence of an increase in the spatial correlation length of the medium-range order is found during hydrogen charging of a Cu-Zr metallic glass and leads to enhanced plastic deformation. |
