Abstract

Using transmission and scanning electron microscopy, a pulsed intense electron beam irradiation of a sintered boron carbide ceramic is shown to lead to the formation of a modified surface layer with a nonporous polycrystalline structure and initiate microtwinning and the formation of extended submicron- and nanocrystalline interlayers along the boundaries of boron carbide crystallites. The observed structural changes lead to an increase in the fatigue life of the modified layer.
