An elastoplastic phase-field model is used to investigate the deformation mechanisms of yttria stabilized tetragonal zirconia in presence defects. A remarkable tension-compression asymmetry detected. higher strength and a lower degree transformation are observed compression than tension. Also, mechanism asymmetric depending on crystal orientation. For some cases (other cases), phase absent tens...

Biaxially-textured epitaxial thin-film hetero-structures of ceria and 8 mol% yttria-stabilized zirconia (8YSZ) were grown using Pulsed Laser Deposition (PLD) with the aim to unravel the effect of the interfacial conductivity on the charge transport properties. Five different samples were fabricated keeping the total thickness constant (300 nm) but with a different number of hetero-interfaces (b...

Electrical-discharge machining (EDM) of advanced ceramics allows the miniaturization parts with complex shapes. Since electrical conductivity is required, non-conductive need a conductive second phase. This work assesses feasibility industrial EDM in yttria-stabilized tetragonal zirconia (3YTZP) composites 20 vol% graphene nanostructures different morphology using energies. The structural integ...

Local atomic structures of Zr and dopant cations in zirconia solid solutions with Fe,03, Ga203, Y203, and Gd203 .have been determined. The Zr ions in both partially stabilized tetragonal and fully stabilized cubic zirconia have their own characteristic structures which are dopant-independent. The dopant cations substitute for Zr ions despite severe local distortions necessitated by the large di...
