Abstract
Synthesis of the Nb-Si in-situ composite was attempted by binder jetting additive manufacturing technology, using Nb powder and liquid Si during infiltration in furnace. The microstructures were examined with scanning electronic microscope, and the phase constituent were analyzed by X-ray diffraction. Furthermore, the effect of using prepared Nb-16Si (at.%) powder mixture as building powder for binder jetting and subsequent melting of internal silicon in furnace on synthesis of the in-situ composite also investigated. After infiltration, the sample mainly consisted of NbSi2 and Si phases. With using of prepared Nb-16Si (at.%) powder and subsequent melting of internal silicon in furnace, microstructure consist of Nbss, Nb3Si, NbSi2 phases.
