Brittleness improvement processing of transparent glass irradiated by electron beam for large-sized liquid-crystal display

Abstract

Influence of electron beam irradiation on hardness, brittleness and fracture toughness of borosilicate glass were studied. Low energy electron beam irradiations is expected for improvement method for material surface. The EB irradiation reduced the brittleness and enhanced fracture diameter, fracture load and fracture toughness of borosilicate glass surface. The fracture toughness enhancement can be explained by stress relaxation induced by increase in density of dangling bonds.
