MICROSTRUCTURAL CHARACTERIZATION OF AA6351 ALLOY BASED COMPOSITES

Abstract

Materials with low weight and good performance are in great demand in applied materials science. Materials of this kind might be used in a wide range of applications, including marine, automotive, and aerospace. In the current study, an aluminium alloy AA6351 was reinforced with different percentages of TiB2 particles (0, 4 and 8 wt percent) that were effectively fabricated by potassium hexafluoro-titanate, exothermic reaction of inorganic salts, and potassium tetrafluoro-borate, with molten aluminium melt to bring out unprecedented properties. The composite's tensile, yield, compression, micro- and macro-hardness were all measured. During the in situ reaction between molten aluminium and the halide salts K2TiF6 and KBF4, TiB2 particles are formed.
