Effects of sheet electron beam irradiation on hardness, brittleness and fracture toughness of borosilicate glass were studied. The irradiation, which was one of short-time treatments at low temperature below boiling point of water, 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.
