Three-dimensional phase-field study of grain coarsening and grain shape accommodation in the final stage of liquid-phase sintering

A 3-dimensional phase-field model is implemented to simulate the grain evolution in the final stage of liquid-phase sintering. The model considers a liquid phase and a polycrystalline solid phase. Results for varying ratios of the solid-solid interface ene ...

Direct Imaging of Dopant Distribution in Polycrystalline ZnO Films

Christophe Ballif, Cécile Hébert, Aïcha Hessler-Wyser, Duncan Thomas Lindsay Alexander, Stéphane Laurent Escrig, Sylvain Nicolay, Monica Morales Masis, Martin Ledinsky, Arthur Brian Aebersold

Two fundamental requirements of transparent conductive oxides are high conductivity and low optical absorptance, properties strongly dependent on the free-carrier concentration of the film. The free carrier concentration is usually-tuned by the addition of ...

Recycling of hydrated cement pastes by synthesis of alpha'(H)-C2S

Franco Alberto Zunino Sommariva, Ricardo Javier Serpell Carriquiry

Hardened cement paste in concrete wastes can be a valuable precursor material for the production of recycled cements. In the reported study, X-ray diffraction data of cementitious materials obtained by thermal processing of hardened pastes were quantitativ ...

Evolution of grain boundary network topology in 316L austenitic stainless steel during powder hot isostatic pressing

Cyril Cayron

The grain boundary network evolution of 316L austenitic steel powder during its densification by hot isostatic pressing (HIPing) was investigated. While the as-received powder contained a network of random high angle grain boundaries, the fully consolidate ...

Atomistic mechanisms of hydrogen embrittlement

Ali Tehranchi

The detrimental effects of the H on the mechanical properties of the metals are known for more than a century. One of the most important degradation mechanisms is H embrittlement (HE). In this thesis, we examined a few famous proposed mechanisms in the fie ...

First-principles calculations of stacking fault energies in Mg-Y, Mg-Al and Mg-Zn alloys and implications for < c plus a > activity

William Curtin, Binglun Yin, Zhaoxuan Wu

Mg-3wt.%RE alloys show substantially enhanced < c + a > activity as compared to pure Mg or other Mg-Al, Mg-Zn alloys of similar grain sizes. Activation of < c + a > slip has been postulated to be associated with the reduction of the basal Li stacking fault ...
