Correlating work hardening with co-activation of stacking fault strengthening and transformation in a high entropy alloy using in-situ neutron diffraction

Article using in-situ neutron diffraction to correlate SF strengthening to work hardening behavior in a low SFE Fe40Mn20Cr15Co20Si5 (at%) high entropy alloy, SFE ~ 6.31 mJ m−2. Cooperative activation of multiple mechanisms was indicated by increases in SF strengthening and γ-f.c.c. → ε-h.c.p. transformation leading to a simultaneous increase in strength and ductility. The present study demonstrates the application of in-situ, neutron or X-ray, diffraction techniques to correlating SF strengthening to work hardening.

Insights into the mechanisms controlling the residual corrosion rate of borosilicate glasses (open access)

Insights into the mechanisms controlling the residual corrosion rate of borosilicate glasses

Article examining the glass durability and residual rate of borosilicate glass. The authors focus on the behavior of the soluble elements of the International Simple Glass (B, Na, and Ca) to show that the residual rate is controlled by the behavior of B, a glass former supposed to dissolve instantaneously when in contact with water and thus widely considered as an ideal tracer. The article demonstrates that B release is controlled by multiple processes highly dependent on the pH. A new paradigm, including B as a key element of the system, is proposed to develop a comprehensive model for the corrosion of borosilicate glass.

Cache-Aided General Linear Function Retrieval (open access)

Cache-Aided General Linear Function Retrieval

This article designs a novel coded caching scheme that outperforms uncoded caching schemes that either use unicast transmissions or let each user recover all files in the library. It extends the scope of the authors’ past work that only considered the class of linear functions that operate element-wise over the files.
