摘要：
It has been proved that the addition of Fe-Ti inoculant to chromium cast iron changes the structure of castings. The said operation increases the number of crystallization nuclei for the dendrites of primary austenite. In this case, due to a similar behaviour of crystal lattice, titanium carbides act as substrates for the nucleation of primary austenite. The more numerous are the dendrites of primary austenite, the more refined is the structure, and the higher are the mechanical properties. Fractures of castings after Fe-Ti inoculation show different fine-grained structures.
