The influence of thermal gradient, overlap, and re-melting of the previous layers on the microstructure of TiC/Ti6Al4V matrix composite samples was analyzed using the scanning electron microscope (SEM). The microstructure showed that the TiC/Ti6Al-4V composite samples are composed of undissolved TiC, in-situ TiC (eutectic TiC and primary TiC), a Ti and ß Ti. While martensite microstructure was observed on the Ti-6Al-4V alloy samples. It was observed that the single-track and single-layer composite samples are consists of blocky TiC, granular eutectic TiC, chain-shaped eutectic TiC and dendritic primary TiC phases. While the cube composite sample shows granular primary TiC and dendritic primary TiC. Dendritic primary TiC is observed in all composite samples.FulltextenLaser metal depositionLMDMicrostructure evolutionTiC/Ti-6Al-4VConference PresentationNomqonde, B., Mashinini, P., Lekoadi, P.
