Hafnia and hafnia-toughened ceramics
J. Wang,H. P. Li,R. Stevens +2 more
TL;DR: In this article, a review of the science and technology of HfO2 and hafnium-based materials in terms of processing, phase transformation, microstructure, and mechanical properties is presented.

Crack healing and stress relaxation in Al2O3-SiC nanocomposites
TL;DR: In this paper, the crack-healing behavior of Al{sub 2}O{sub 3} and Alsub 2 O{Sub 3}-SiC nanocomposite was studied using Vickers indentations to generate precracks.

Crack-healing behavior of Al2O3 toughened by SiC whiskers
TL;DR: In this article, Al2O3 reinforced by SiC whiskers was hot-pressed to investigate the crack-healing behavior of SiC-W. The results showed that SiC made their Al 2O3 tougher, and the surface cracks with length of 2 c = 100 μm could be healed at 1200° or 1300°C for 1 h in air.

High-Temperature Healing of Lithographically Introduced Cracks in Sapphire
Jürgen Rödel,Andreas M. Glaeser +1 more
TL;DR: In this paper, a method for producing controlled geometry, controlled-crystallography, crack-like defects using photolithography has been developed, which has been applied to sapphire, and used to study crack healing behavior at 1800°C.

Strength recovery by diffusive crack healing
Anthony G. Evans,E.A. Charles +1 more
TL;DR: In this paper, the strength recovery model is shown to be consistent with the available strength recovery data, which is consistent with previous work on diffusive crack recession in polycrystalline ceramics.
