Novel microstructural growth in the surface of Inconel 625 by the addition of SiC under electron beam melting

► Electron beam melting is successfully used to grow the novel structure during the reinforcement of SiC in Inconel 625 alloy. ► Novel structures like rod/wires, bamboo, pyramid, ribbon, terraces and tweezers are formed. ► The microhardness of the modified surface enhanced about two times as compared to the as-received alloy. ► Changes in the composition as well as the cooling rate affect the morphology of re-solidifying melts.
