摘　　要：Peritectic reaction is seriously limited by solute diffusion, it can rarely be completed during practical materials processing.One side, the grain refinement of primary phase dendrites resulting from high undercooling condition facilitates the completion of peritectic transformation. Otherwise, those peritectic alloys with positive mixing enthalpy usually displayPeritectic reaction is seriously limited by solute diffusion, it can rarely be completed during practical materials processing. One side, the grain refinement of primary phase dendrites resulting from high undercooling condition facilitates the completion of peritectic transformation.
