The main achievement of this research is revealing the atomic-scale origin of the low grain-boundary (GB) resistance in air-quenched (Li0.375Sr0.4375)(Ta0.375Nb0.375Zr0.125Hf0.125)O3 (LSTNZH) perovskite solid electrolyte in charge perspective and...
•In IRG-1, Luo, Xin, Rupert, and their students have discovered Ni activated sintering of MoNbTaW guided by a computed grain boundary “phase” (complexion) diagram. •This collaborative study made the first observation of solid-state activated sintering in a...
Grain boundaries often transition between different states, which has important implications for material stability as well as key properties such as strength and fracture resistance. In this study, atomistic computer models were used to study grain boundary...
•Heat treatment-induced phase transformation enhances the electronic conductivity of grain interior in entropy stabilized oxides (ESOs) by tuning grain defect chemistry, as second phases segregate to the grain boundaries (GBs). •This work demonstrates the potential to...
Understanding phase stability of CoCrNi alloy is necessary to ensure that no detrimental phases form when held for long period of time during the potential application temperature •A long-term annealing at 450 °C for 350 hrs was employed to explore the phase stability...
