In structure, matrixes and borides were included in as-cast condition and the matrixes were changed with different alloying elements and quantity. Borides were distributed in the shape of continuous net in the structure of high boron iron-base alloy. When the melt was solidified in metal mould and sand mould respectively, the grain size of austenitic primary crystal decreases with the cooling rate increase. In addition, the morphology of borides was changed greatly. After heat treatment, borides of samples made of sand mould were changed little, otherwise, borides of samples made of metal mould were changed to granulation shape and the impact toughness was increased by 60%..
