In the present work particulate reinforced Al1050-5wt.%TiB2 in-situ composites were processed under three time of 5 minutes, 10 minutes and 15 minutes of intermittent stirring was investigated. The microstructural characterization of the prepared composites was systematically examined by optical, electron microscopy and X-ray diffraction. Composite processed at 5 minutes of Intermittent stirring showed inhomogeneous distribution of particles present along with the unreacted salt and slag. Moreover, along with TiB2 particles the presence of intermediate phases like Al3Ti and AlB2 confirm that the reaction between the salts and the melt was incomplete. The composite processed 10 minutes of intermittent stirring showed uniform distribution of particles. Composite prepared with 15 minutes of Intermittent stirring of the composite also showed the presence of both intermediate phases along with fine TiB2 particles confirmed that high melt stirring conditions hindered the formation of TiB2 particles. The microstructural observations were confirmed by the X-ray diffraction studies. The percentage of porosity present was found to be higher among the composites prepared with 5 minutes of intermittent stirring.
