摘要：
TiB2 particles are dispersed into aluminum alloys to improve their mechanical properties. The TiB2 particles are produced in situ by chemical reactions of a mixture of K2TiF6 and KBF4 salts with aluminum and are subsequently dispersed in the aluminum alloys as reinforcement. Through adjusting the processing chemistry by adding different alloying elements, TiB2 particles can be tailored to desired morphologies and sizes. The results are discussed in view of interfacial energy and heterogeneous nucleation of aluminum grains in solidification.
