Abstract

In order to evaluate its machining and mechanical capabilities, a hybrid aluminium metal matrix composite was created for this investigation. Composites made of an aluminium metal matrix are reinforced with silicon carbide and titanium di boride. The shape and structure of the composites and improved particle dispersion were thoroughly examined using optical microscopy. Using a Vickers hardness testing apparatus, the cast composite underwent the hardness test to assess its hardness. The results of the hardness tests show that the hardness value is increased by SiC and TiB2 reinforcing. The hardness rating decreases when the reinforcement is increased by up to 15%, though. Mechanical testing was done on tensile samples created from cast composite specimens of diverse compositions. According to the results of tensile tests, applying reinforcement SiC to the base metal provided the composite 20% more strength, however adding TiB2 decreased the strength by 50–60%. Wear test analysis was the method used to study the TiB2 wear resistance behaviour. The addition of TiB2 increased the composite's wear resistance, according to wear tests. The samples made of cast composite were carefully machined. The impact of machining parameters including cutting speed (s), feed rate (f), depth of cut (d), and TiB2 weight percentage on surface roughness (Ra) throughout a turning operation was investigated. The proportion of TiB2 reinforcement, having a contribution of 38.86%, is the single most important parameter impacting surface quality, according to the examination of variance approach. Research on tool wear was conducted to examine tool wear patterns, built-up edge formation, the impact of TiB2 on tool wear, and how these factors affect the surface's cast composite quality. Surface quality is affected by TiB2's increased tool wear, poor surface polish, and built-up edge formation.
