Abstract

The homogeneous and quick treatment of 100 keV class electron beam irradiation (EBI) improved the resistance to impact fatigue indicated by the critical collision number (Nc) of impact fracture of PZT (Pb(Nb2/3Ni1/3)O3-Pb(Zr1/3Ti2/3)O3) ceramics, although an additional dose decayed them. An optimal dose of 0.086 MGy-EBI apparently improved the Nc and ECi of PZT. It could be explained by shortening the lattice constant after the collision for the PZT irradiated with the optimal dose.
