| Summary: | 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. Changes in conditions of solidification, as a result of
adding vanadium to Fe-Cr-C white iron, influence the change in composition of
austenite, which manifests itself in the form of different degrees of
transformation of austenite. |
