stainless steel with TiC additions were studied by theory and experiment. Using an "edge?to?edge matching" model, a 5.25 mismatch between TiC(FCC structure) and ferritic stainless steel(BCC structure) was identified, which met the mismatch requirement for the heterogeneous nucleation of 430 ferritic stainless steel. TiC was found to be an effective nucleation site for the formation of acicular......
