Tailoring the grain boundary structure and chemistry of the dendrite-free garnet solid electrolyte Li6.1Ga0.3La3Zr2O12

NPG Asia Materials
Garnet-type Li6.1Ga0.3La3Zr2O12 (LGLZO) exhibits high ionic conductivity and extremely low electronic conductivity. The electrochemical properties strongly depend on the characteristics of the grain boundaries and pores in the oxide–ceramic electrolyte ...

Increasing the content of CSL grain boundaries in ferritic steel through grain boundary engineering

Journal of Materials Research and Technology
Coincidence Site Lattice (CSL) grain boundaries are special boundaries that enhance a material’s resistance to hydrogen embrittlement, corrosion, and fracture.

On the effect of boron on the mechanical properties of a new polycrystalline superalloy

MATEC Web of Conferences, 2014
Boron is used as a grain boundary strengthener in the nickel-based superalloys, but the reasons for its effect and the optimum quantities which need to be added are not well understood.

Modeling the oxidation process of TiAl and Ti₃Al intermetallic compounds due to grain-boundary diffusion of oxygen

Учёные записки Казанского университета: Серия Физико-математические науки
A diffusion-kinetic model was proposed to analyze the oxidation process in a nanostructured material with explicit identification of grain boundaries. It was assumed that oxygen migrates faster along the boundaries than it does in the grain volume.

On a relationship between grain boundary free energy, grain boundary segregation, and grain boundary diffusion

We present a detailed analysis of the universal relationship between grain boundary (GB) free energy and GB self-diffusion coefficient derived by Borisov et al. (1964). This relationship was expressed by a simple equation that was used in many publications to predict GB energies on the basis of experimental diffusion data.

Formation mechanism of multiple spallation and its penetration induced by shear localization in NiTi alloy under implosion loading

Matter and Radiation at Extremes
This study uses nonequilibrium molecular dynamics simulations to explore the dynamic failures and deformation mechanisms of a cylindrical shell composed of nanocrystalline nickel–titanium alloy under implosion loading.
