Description	Journal: Iop Conference Series: Materials Science and Engineering In this study, in situ Titanium-tri-aluminide $(Al_{3}$Ti) particles reinforced Al 6061 alloy matrix composites were fabricated by the reaction of potassium hexafluorotitanate $(K_{2}TiF_{6}$) inorganic salt with molten Al 6061 alloy via liquid metallurgy route. The development of in-situ $Al_{3}$Ti particles and their effects on the mechanical properties such as yield strength (YS), ductility, ultimate tensile strength (UTS) and hardness, and microstructure of Al 6061 alloy were studied. It was observed from the results that in-situ formed $Al_{3}$Ti particles were blocky in morphology whose average size was around 2.6 ± 1.1 μm. Microstructure studies showed that grain size of Al matrix was reduced due to the nucleating effect of $Al_{3}$Ti particles. It was observed from the mechanical properties analysis that when the volume fraction of $Al_{3}$Ti particles was increased, the hardness, UTS and YS of the composites were also increased as compared to that of Al 6061 alloy. An improvement in ductility was observed with the dispersion of $Al_{3}$Ti particles in base alloy which is contrary to many other composites.
