Abstract

The electron beam welding of WC-Co cemented carbide and 40Cr steel was studied in this paper. The mechanism of microstructure evolution in the joint was analyzed. The weld was mainly composed of (Fe, C) martensite and η phases consisted of Fe₃W₃C. But the eutectic reaction occurred in the weld when the heat input was large, and then eutectic phases composed of (Fe, C) and η phases were generated. With the decrease of heat input, the content of η phase would decline.
