%X The present study was devised to analyse the strengthening mechanisms of a reinforced AlCu5MgTi alloy. TiB2 particulates were created into the aluminium alloy in an in situ process were titanium and boron containing salts added into melt aluminium reacted and formed TiB2 particulates following long known reactions. The obtained material was subsequently cast in order to obtain samples and characterise them. The metallurgical analysis showed that, as foreseen, TiB2 particulates play an important role in the precipitation of the different phases of the alloys as well as in the reduction of grain size and porosity. It was clearly shown that the elongation values got increased (46% in the as cast condition and 63% in the T6 thermally treated specimens). The observed microshrinkages were also much less abundant in the case of the reinforced materials. This latter effect is related to the shortening of the solidification interval.
