In-situ formed TiB2 particles are dispersed into aluminum alloys to improve their mechanical properties. The TiB2 particles are produced by chemical reactions of K2TiF6 and KBF4 with aluminum and are subsequently dispersed in the aluminum alloys as reinforcement. Through adjusting the processing chemistry of the molten salts, TiB2 particles can be tailored to desired morphologies and sizes for particular properties. To improve the dispersion of the TiB2 particles, titanium is added as alloying element to promote the nucleation of aluminum grains on the TiB2 particles. The results are discussed in view of surface energy and heterogeneous nucleation of aluminum grains in solidification.
