MILESTONES OF THE RESEARCH

  • 15 seconds up to failure (2.5 mm/min. crosshead speed) 4-points bending tests on PSZ (yttria partially stabilised zirconia).
  • Acoustic emission acquisition of the energy released from failure and localisation of the starting point of fatal crack.
  • SEM (surface or volume defects, some porosity and abnormal grain growth).
  • Diffractographs showed the presence of phosphate crystals impurities.
  • Collaboration: ENEA-Casaccia
