This paper addresses the problem of enlarging the strength of Ti‐6Al‐4V titanium parts fabricated by wire‐based electron‐beam additive manufacturing (EBAM) technology. The investigations on microstructure and phase composition of wire‐based EBAM Ti‐6Al‐4V samples as well the as EBAM TiC x / Ti‐6Al‐4V ones fabricated by electron beam melting of titanium Ti‐6Al‐4V wire with simultaneous supply of TiC powder were performed. It is shown that adding of TiC powder into a molten pool significantly affects the microstructure and volume fraction of retained β phase in the EBAM‐built parts. The main conclusion made postulates that the combination of wire feeding–based EBAM and direct metal deposition technology, which utilizes a feed nozzle to supply the ceramic powder into a molten pool, provides an ample opportunity to produce EBAM TiC x / Ti‐6Al‐4V samples with increased microhardness and tensile strength.
