This study investigated the influence of the duration and high-voltage magnitude of electrical discharges on the formation of TiC reinforced iron composite through preprocessing by high-voltage electrical discharges of Ti and Fe powders. Mixtures of titanium and iron powders were activated in burning oil by high-voltage electrical discharges with different electrical discharge numbers. X-ray diffraction showed that with increasing electrical discharge numbers, the crystallite size of the titanium and iron powder particles decreased to nanometer range, accompanied by an increment in internal strain. The preprocessing by high-voltage electrical discharges of Ti powder particles in burning oil resulted in the formation of titanium carbide phases as confirmed by X-ray diffraction, scanning electron microscope analysis. The preprocessed powders were compacted by high voltage consolidation and suitable operating parameters were defined. Microstructures and hardness of consolidated specimens were studied.
