Deformation mechanisms in yttria-stabilized cubic zirconia single crystals. International Journal of Materials Research, 101 (10), 1211-1214. https://doi.org/10.3139/146.110399.1862-52822195-8556https://hdl.handle.net/11441/156615This work attempts to give a unified picture of the microscopic mechanisms which control the plastic deformation in yttria-stabilized cubic zirconia single crystals, particularly for the soft orientation (uniaxial compression along the [1̄* * *2] crystallographic axis) at low, intermediate and high temperatures while also reviewing and updating the existing data for different yttria contents (9.4-32 mol.%). The controlling deformation mechanisms are: internal friction within the crystal lattice (Peierls mechanism at low temperatures), pinning of dislocations by localized obstacles and long-range interaction between dislocations (intermediate temperatures) and dislocation viscous glide and climb (recovery creep) at higher temperatures. New aspects of the Portevin-le Chatelier phenomenon during viscous glide, due to the pinning and unpinning of dislocations from their defect clouds (yttrium substitutional atoms), are included.application/pdf14 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/CreepDeformation mechanismsPortevin-le ChatelierSingle crystalsYttria-stabilized cubic zirconiainfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccesshttps://doi.org/10.3139/146.110399
