Abstract

Influences of electron beam irradiation on impact fracture energy indicated by impact value are studied for alkali free glass. The irradiation, which is able to be one of short-time treatments, reduced the brittleness and increased the impact value of alkali free glass. The impact value enhancement can be explained by stress relaxation induced by increase in density of dangling bonds.
