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 …

Air plasma sprayed thermal barrier coatings (TBCs) are widely used in gas turbines to
provide thermal insulation for the metallic engine components. During service, the multi …

Zirconia ceramics have found broad applications in a variety of energy and biomedical
applications because of their unusual combination of strength, fracture toughness, ionic …

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 …

Three types of CeO2–ZrO2 (Ce: Zr= 1: 1 molar ratio) compounds with different oxygen
storage/release capacities (OSCs) were characterized by means of the Ce K-edge and Zr K …

The desire to improve the corrosion resistance of Zr cladding material for high burn-up has
resulted in a general trend among fuel manufacturers to develop alloys with reduced levels …
