Abstract

Abstract Single crystals of 24–32 mol% yttria fully stabilised cubic zirconia have been deformed in compression along 〈1 1 2〉 at T=1400–1500 °C with strain rates ε ̇ ranging from ∼10 −8 to ∼10 −4 s −1 (nominal stresses 100–320 MPa). The deformation mechanisms are discussed in terms of macroscopical and microscopical parameters.
