Hugoniot-measurement study of the stabilized zirconia single crystal

Abstract

Hugoniot-measurement experiments of the Y2O3-doped (9.6 mol%) stabilized zirconia in the pressure range up to 120 GPa were performed by using single crystals to study cubic directly the yielding property, phase transition and their crystal-axis effects to shock propagation. The Hugoniot parameters were measured by means of the inclined-mirror method combined with a powder gun and a two-stage light gas gun in the impact velocity range of 1.2-3.6 km/s. The Hugoniot-elastic limits (HEL) parallel to (100) and (110) axes showed large difference. Above the HEL’s, the Hugoniot data parallel to (100) and (110) axes converged each other, and showed large relief to an isotropic compression state. In addition, this material transformed to the high pressure phase up to 70 GPa.
