Indirectly probing the structural change in ion-irradiated Zr-Based metallic glasses from small scale mechanical tests

Absolute radiation tolerance of amorphous alumina coatings at room temperature

“…Presented study complements previous research in the field of radiation resistance of amorphous materials [45,48,62,63,49,50,55,[57][58][59][60][61]. One of the main issues in the knowledge in this field is the lack of well-established correlation between mechanical behavior and the atomic-level structure.…”

Indentation of glasses

“…These variations were attributed to the mobile-hydrogen-assisted softening and immobile hydrogen trapped inside Zr-rich interstitial sites that results in a densely packed structure, respectively [273,274]. Irradiation can tailor the amorphous structure, since the bombardment of MGs with energetic particles such as electrons, neutrons, and ions induce structural heterogeneities [275,276]. Irradiation effects on the mechanical behavior of MGs was also examined via nanoindentation [276][277][278].…”

Cryo-Casting for Controlled Decomposition of Cu–Zr–Al Bulk Metallic Glass into Nanomaterials: Implications for Design Optimization

“…Moreover, the typical size of the nanoindented zone is several microns; thus, parameters such as hardness, Young’s modulus, and strain rate sensitivity will be based on the contribution of many Cu- and Zr-rich regions. It is also important to note that the localized shear-induced deformation with a very limited amount of plasticity in millimeter-sized samples might turn into a (homogeneous) deformation with high plasticity depending on the plastic zone size of the chosen metallic glass as well as preparation and testing conditions of micro/nanopillars for compression or microsamples for tension. − In this respect, in free-standing NiZr thin films with nanoscale heterogeneities with a characteristic length scale of 2–3 nm, the activated and evolved STZs do not percolate and cause catastrophic failure . The complex network generated by this spinodal-like network of density/chemical fluctuations with randomly oriented interfaces was asserted to play a critical role in increasing the resistance against shear band propagation.…”
