Tetragonal zirconia: Wet chemical preparation, mechanical and electrical properties [PDF]
, 1985 Yttria-stabilized zirconia powders were prepared in the composition range of 3 to 13 at% yttria. The hydrolysis-gel precipitation technique was used, starting from metal alkoxides or chlorides.

Toughening materials: enhancing resistance to fracture
Philosophical Transactions of the Royal Society A, 2021 It has been said that ‘God invented plasticity, but the Devil invented fracture!’ Both mechanisms represent the two prime modes of structural failure, respectively, plastic collapse and the rupture/breaking of a component, but the concept of developing ...

Ultra-Tough Polylactide/Bromobutyl Rubber-Based Ionomer Blends via Reactive Blending Strategy
Frontiers in Chemistry, 2022 A series of ultra-toughened sustainable blends were prepared from poly(lactic acid) (PLA) and bromobutyl rubber-based ionomers (i-BIIRs) via reactive blending, in which dicumyl peroxide (DCP) and Joncryl®ADR-4440 (ADR) were used as reactive blending ...

The contribution of 211 particles to the mechanical reinforcement mechanism of 123 superconducting single domains [PDF]
, 2003 Hardness and fracture toughness of Dy-123 single-domains were studied by Vickers micro-indentation. A significant anisotropy of the mechanical properties was observed. Hardness tests give higher values when performed in (001) planes rather than in planes

Toughening Mechanisms of Rubber Toughened PMMA.
JSME International Journal Series A, 1999 Toughening mechanisms of three types of rubber toughened poly(methyl methacrylate)(RT-PMMA) were investigated under mode I loading condition by optical and electron microscopies in conjunction with the quantitative evaluation of mode I fracture toughness.
