主　　题：spray forming TiB2 particulate coarsening semi-solid state 

摘      要：An in situ reaction and spray forming technique were employed in the synthesis of 2% TiB2/Si-30Al *** formation mechanism of TiB2 particulates was explained based on thermodynamic *** modification of the primary Si in the Si-30Al alloy was interpreted in the light of the knowledge of atomic *** experimental results show that adding 2% TiB2 to the Si-30Al alloy can effectively refine the primary ***,the coarsening and growth of primary Si phase in its semi-solid state was retarded effectively due to the existence of the TiB2 particulates.
