Mechanisms of tetragonal phase stabilisation, at room temperature, in nanocrystalline (<
100 nm), submicrometre-sized (100 nm–1 μm), and bulk zirconia (ZrO2)(> 1 μm) are …

Ceramic thermal barrier coatings (TBCs) have attracted significant research attention owing
to their utility in the thermally insulating alloy components of gas turbines and aircraft …

The recognition of the potential for enhanced fracture toughness that can be derived from
controlled, stress‐activated tetragonal (t) to monoclinic (m) transformation in ZrO2‐based …

The dopant-induced ferroelectric HfO 2 formation has been systematically investigated by
using cation (Sc, Y, Nb, Al, Si, Ge, and Zr) and anion (N) dopants. Both differences and …

The microscopic mechanism leading to stabilization of cubic and tetragonal forms of zirconia
(ZrO2) is analyzed by means of a self-consistent tight-binding model. Using this model …

Surface engineering is now a key materials technology in the design of future advanced gas-
turbine engines. This article focuses on coating systems for hot-gas-path components, which …

Nanostructured CeO2–ZrO2 mixed oxides have attracted great interest in the past 10 years,
in particular as redox or oxygen storage promoters in the three-way catalysts. However, it …

RAIN BOUNDARY mobility can be influenced by dopants in two distinct ways. First, grain
boundary diffusivity of host ions is altered through defect chemistry and dopant-defect …

Computer simulation techniques have been used to investigate the defect and transport
properties of the zirconia (ZrO2) oxygen-ion conductor. First, a wide variety of low-valent …

An examination of the ZrO2–YO1. 5–TaO2. 5 system reveals several promising attributes for
use in thermal barrier coating applications. The rather unique presence of a stable, non …
