A new type of grain reinforcing cast composite is introduced. The reinforcing component is the coarse steel grain (0.6∼1.0mmϕ) with the matrix of tin bronze. The wearing resistance of this material is 10 times as much as the matrix and regarding the tensile strength, 3 times. In this paper, the interface behaviour between grains and the matrix is emphasised. The results show the formation of an interface layer, caused by the diffusion of Fe and Cu, which strengthens the bonding.
