Preparation method of local reinforced steel base composite material for synthosizing TiC particle in mould

A technology for preparing the steel-based composition reinforced locally by the TiC particles which are synthesized in mould includes such steps as uniformly mixing Al powder, C powder and Ti-Fe powder, die pressing to obtain prefabricated block, vacuum heating for removing moisture and gas while passivating, putting the fabricated block at the position in mould, where is needed to reinforce, pouring molten steel in the mould, and high-temp synthesis reaction to generate the reinforcing phase (TiC particles).
