In this paper, the origin of the threshold stress in pure 3 mol %-yttria tetragonal zirconia polycrystals (YTZP) is analysed in detail. At this regard, the two explanations reported in literature are discussed thoroughly. One of them invokes dislocation activity as the origin for such quantity, wher
High-temperature mechanical spectroscopy was performed in pure 3Y-TZP, i.e. 3-mol% yttria-stabilized polycrystalline tetragonal zirconia, in 3Y-TZP doped with multiwalled carbon nanotubes and in 3Y-TZP doped with silicon carbide whiskers. Silicon carbide doping results in an increase in the high-tem
