| Abstract: | Based on experimental investigation of the austenite decomposition and microstructure of vanadium and titanium containing alloys,the solute drag-like effect(SDLE ) of carbide-former elements and the effect of carbide-former on the formation of granular bainite structure have been discussed with detail .It is demostrated that the carbide-former(vanadium and titanium)possesses potential strong SDLE as long as the alloy contents are higher enough and no carbides precipitate at or before the early stage of austenite decomposition. Both strong and weak carbide-former can be in favor of the formation of granular bainite structure in Fe-C alloys. |
