Abstract: Disclosed is a method for preparation of an aluminum matrix composite including preparation of in-situ reaction mixed salt, preparation of a TiB2 enhanced 6061 aluminum matrix composite and ultrasonic treatment of a composite melt. The obtained composite contains TiB2 enhancing particles which are fine in size and uniform in distribution and may remarkably improve the mechanical performance indicators of a matrix alloy. In the TiB2 enhanced 6061 aluminum matrix composite according to the present disclosure, the size of the TiB2 enhancing particles is 200-500 nm and the particles are uniform in distribution in the matrix alloy.
