In-situ ZrB2/AZ91 magnesium matrix composite was successfully synthesized with Al/K2ZrF6+NH4BF4 by Direct Melt Reaction (DMR). The microstructures of the ZrB2/AZ91 magnesium matrix composite fabricated by direct melt mixing method were investigated. The results show that the size of ZrB2 particles is less than 1μm and even reaches to 100nm and the shape, amount and size of the β-Mg17Al12 phase in magnesium matrix composite have been greatly changed due to ZrB2 heterogeneous nuclei.
