Current knowledge of toughening mechanisms in zirconia ceramics is reviewed, with
particular emphasis on the transformation toughening of yttria-stabilised polycrystalline …

To understand the stress evolution and failure mechanisms of thermal barrier coatings
(TBCs), finite element simulations are an invaluable tool. Simulations are especially useful …

A simple, fast and upscalable method is described to produce graphene/alumina (G/Al 2 O
3) composites by spark plasma sintering (SPS) with a significant improvement on both …

The effect of heat treatment on the grain size, phase assemblage, and mechanical
properties of a 3 mol% Y‐TZP ceramic was investigated. Specimens were initially sintered …

Indentation fracture models of ductile machining in hard and brittle materials are critically
appraised. Relations obtained in a seminal study for critical depths of cut below which …

Nanocrystalline tetragonal zirconia samples are shown to reach toughnesses between 16
and 17 MPa· m1/2, provided the conventional levels of 3 mol% yttria additive are lowered to …

Nanocrystalline 3Y-ZrO {sub 2} with densities ranging from 90.4% to 98.7% of theoretical
and grain sizes from 55 nm to 160 nm were tested by Vickers indentation. The hardness of …

Standard mixtures of tetragonal and monoclinic zirconia powders have been carefully
prepared in order to cover the complete weight range from 0% to 100% of monoclinic phase …

Engineering ceramics with high strength, toughness and electromagnetic interference (EMI)
shielding effectiveness (SE) are highly desirable as electromagnetic protecting material in …

The relationship between fracture toughness and Yttria content in modern zirconia ceramics
was revised. For that purpose, we evaluated here 10 modern Y 2 O 3-stabilized zirconia …
