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
