Nanostructured ceramic materials have various structural and functional applications. However, the intrinsic brittleness of ceramics and difficulty in fabricating well densified nanoceramics limit our fundamental understanding on deformability of nanoceramics, especially at high temperature. Here, we present the high temperature in-situ microcompression studies on nanosized yttria-stabilized zirconia (YSZ) rapidly densified by flash sintering technique at low sintering temperature. The YSZ exhibits high inelastic strain due to transformation induced-plasticity. At higher temperatures, crack nucleation and propagation are significantly retarded. The influence of test temperature on deformation mechanisms of YSZ is discussed.
