Vanadium - Transforming Possibilities

Vanadium Titanium Structural Steels

Abstract:

The combination of vanadium and titanium additions to microalloy steels creates a very at­tractive potential, as the titanium offers the opportunity to produce a fine grain austenite dur­ing rolling and also a fine grain size in the fusion line region of the HAZ, thus increasing the toughness of welds, while the vanadium produces increased strength as a result of precipitation in the ferrite, and also contributes to the toughness of welds through the promotion of intragranular ferrite in the fusion line region of the RAZ.
