The addition of 2% V affects the solidification process and changes the transformation characteristics of austenite in hypoeutectic white cast iron containing 19% Cr and 2.9% C. DTA analysis reveals that vanadium reduces the solidification temperature interval in tested alloy. The narrowing of the solidification temperature interval and the formation of vanadium carbides favours the appearance of a finer structure. Also, the phases volume fraction changes, i.e. the primary γ-phase fraction decreases and the amount of M7C3 carbide increases. Further, changes in conditions of solidification, influence the change in composition of austenite. Type and degree of transformation of austenite in the course of cooling after solidification in these alloys depend on chemical composition of austenite.
