Abstract

In this study, NbB2 particle reinforced composites in Al matrix were produced by in-situ method. The effects of particle reinforcement at different ratios and production time on composites were investigated. The size and spatial distribution of the formed particles were examined, and the effect on grain size and hardness was determined. As a result of the studies, it was determined that the mixing time is as important as the alloying ratio in the formation of particles, and the best values were obtained in the 3.75% NbB2 added composite, which was formed after 1.5 hours of mixing. In this composite, the grain size was reduced to 112 μm and the hardness was 306.4 MPa.
