damage. The main effort is now focused on developing ceramics with difficult-to-obtain …

Silicon (Si) microfabrication techniques, derived from the microelectronics industry, have
enabled the development and commercialization of microelectromechanical systems …

Experimental observations of the tetragonal phase transformation behavior in polycrystalline
zirconias and the related toughening contribution are presented. An analysis which …

Crack‐tip bridging by particles is considered to be one of the primary strengthening
mechanisms of ceramic nanocomposites. Small, brittle particulate inclusions have been …

The alumina scales on a variety of high-temperature alloys are found to fluoresce when
illuminated with light having a frequency greater than 18,000 cm− 1. The fluorescence …

A general methodology is developed for determining the state of stress and the numerical
value of the stresses from observed shifts and broadening of optical fluorescence lines. The …

Results of sliding wear tests on three alumina ceramics with different grain sizes are
discussed in the light of crackresistance (R‐curve, or T‐curve) characteristics. The degree of …

In the search for novel sodium-ion conductors to be used in batteries for grid application, the
thoroughly studied class of NASICON materials is of great interest due to compositional …

The toughness of a brittle material may be substantially improved by adding small quantities
of tough particles to the solid. Three mechanisms may be responsible. Firstly, the front of a …

The residual stresses created in polycrystalline aluminum oxide as a result of its constrained
anisotropic thermal contraction are measured with the technique of piezospectroscopy using …
