Microstructural Transformation of Titanium-Boron Carbide (B₄C) Powder Mixture during Spark Plasma Sintering

Abstract:

Present study investigates the microstructural evolution and in-situ formation of Ti/(TiB+TiC) composite. The sintered compacts are having near theoretical density. The relative density of Ti/(TiB+TiC) composites decreases with increasing TiB and TiC content.The phase evolutions of TiB and TiC according to the in-situ reactions are analyzed by X-Ray diffraction technique (XRD). Optical microscope (OM) and Energy dispersive spectroscope (EDS) observations of the Ti/(TiB+TiC) composites shows the presence of TiC and TiB reinforcements as equiaxed and needle like structures respectively.
