Abstract
The present study is concerned with the processing and the microstructural analysis of surface alloyed materials with TiB₂ powders using irradiation of high-energy electron beam. The mixtures of TiB₂ powders and flux were deposited on a plain carbon steel plate, and then electron beam was irradiated on these mixtures using an electron beam accelerator. The microstructures of the irradiated surface layers were examined by optical and scanning electron microscopy. A few residual micropores were found in the sample processed without flux, but their number was decreased in the samples processed with a considerable amount of flux. As a result of irradiation, the Ti content was homogeneously maintained throughout the melted region, whose hardness was greatly improved. This was associated mainly with the microstructural modification including the segregation of Ti and B along solidification cell boundaries and the formation of fine Ti(C,M) particles.
