▪ Abstract Over the past decade, significant progress has been made in understanding the
rheological properties of partially molten mantle rocks. Laboratory experiments demonstrate …

Grain boundaries exhibit phase-like behavior in which their structure, chemistry and
properties may change discontinuously at critical values of thermodynamic parameters such …

Interfaces such as grain boundaries (GBs) and heterointerfaces (HIs) are known to play a
crucial role in structure-property relationships of polycrystalline materials. While several …

The grain boundary electrical properties of high purity ceramic materials doped with 2, 3,

Although the presence of siliceous phases is a major cause of the grain boundary blocking
effect in doped zirconia (ZrO2), the grain boundary resistivity also appears to be significantly …

Grain boundary structure, chemical composition, and bonding state in superplastic SiO2-
doped TZP and undoped TZP were investigated by high resolution electron microscopy …

In recent decades researchers have revealed a rich variety of grain boundary segregation
phenomena, including interfacial phase, or complexion, transitions. Grain boundary …

The sinterability of yttria-tetragonal zirconia polycrystals (Y-TZP) containing small amounts of
