Abstract

Effect of electron beam (EB) irradiation on bending fracture toughness of a silica-based glass was studied. The EB irradiation enhanced the bending fracture stress and strain, which were higher than those before EB irradiation. The EB-reinforcement was explained by the stress-relaxation of glassy structure.
