The viscous-flow behavior and temperature dependence of the elastic moduli chalcogenide glasses from germanium-selenium system were studied by means homemade high-temperature indentation setup resonant-frequency technique (1--10 kHz), respectively, for temperatures between 0.8 1.2$\phantom{\rule{0.16em}{0ex}}\ifmmode\times\else\texttimes\fi{}\phantom{\rule{0.16em}{0ex}}{T}_{\mathrm{g}}$. softening rates, both in regimes, correlated to network destructuration or reorganization events light...
Abstract An experimental investigation into the variation of mechanical properties (yield stress, yield strain, elastic moduli, hardness) from sub-ambient temperature (77 K) to that just below glass transition temperature, different bulk metallic glasses was conducted. Particular emphasis on constraint factor, ratio hardness compressive which is taken be proxy for dependence pressure sensitive plastic flow. All properties, except decrease linearly, throughout range examined, with and when...
Indentation and scratching tests are carried out on a ZrCuAlNi bulk metallic glass. The bonded interface technique is used to characterize the plasticity mechanisms underneath indentation. Finite-element analyses conducted with Drucker–Prager behaviour law challenge indentation experimental data. relevance of technique, in terms quantitative evaluation, discussed. It also reported that angle value, for which radial bands intersect at surface or it, not constant value depends indenter...
Gel‐derived oxycarbide glasses have atomic network structures similar to that of vitreous silica glass but with carbon‐rich regions consisting CSi 4 tetrahedra and C–Si–O bonds finely dispersed in the glass. Therefore, exhibit so‐called “anomalous” hardness behavior, silica‐rich glasses, a substantial densification–strain component beneath indenter. However, role carbon is twofold: on one hand, covalently bonded atoms slightly affect way modifiers behavior silicate favor “normal” indentation...
