摘要：

In the present study, a surface composite reinforced with TiC particles was fabricated by high-energy electron beam irradiation. Microstructure of the irradiated surface composite is composed of the melted region, the HAZ, and the unaltered region. The melted region mainly consists of radially grown dendrites of TiC particles, rosette-shaped TiC particles, and fine needle-shaped eutectic TiC particles on the bainitic matrix. These carbides improve hardness about four times higher than that of the steel substrate. This surface composite method using high-energy electron beam irradiation holds significant implication for the development of new advanced materials economically.
