Impact of TiB2 Particles on Improving rocessing Parameters of TiB2/Al Metal Matrix Composites

Abstract

TiB2/Al MMCs, which are composite materials consisting of TiB2 particles embedded in an aluminium matrix, exhibit unique properties that make them very favourable for manufacturing highperformance aircraft blades. Nevertheless, the machinability of TiB2/Al MMCs continues to be a hurdle owing to the impact of TiB2 particles, hence restricting the extensive use of these materials. This research effectively examined the influence of TiB2 particles on processing parameters for TiB2/Al MMCs in order to meet manufacturing requirements. In addition, the research sought to determine the most favourable processing settings for these metal matrix composites, taking into account many considerations. The end-process variables, namely surface roughness and material removal rate (MRR), were assessed after the determination of the most favourable cutting velocity, feed rate, and depth of cut. The findings demonstrate substantial deviations from the strengthening of Metal Matrix Composites (MMCs) using titanium diboride (TiB2) nanoparticles. These results provide vital insights for enhancing the machining process of this material.
