摘      要：The effect of chemical composition and processing parameters on the formation of acicular ferrite and/or bainite has been *** particular,this paper deals with the influence that N through its combination with V,as V(C,N) precipitates,has on the decomposition of ***,the intragranular nucleation potency of V(C,N) precipitates is analyzed through the continuous cooling transformation diagrams (CCT) of two C-Mn-V steels with different contents of *** reported in this work allow us to conclude that acicular ferrite can only be achieved alloying with vanadium and nitrogen,meanwhile bainite is promoted in steels with a low level of *** is concluded that higher strength values are obtained in acicular ferrite than in bainitic steel but a similar brittle-ductile transition temperature (BDT),and lower values of impact absorbed energy (KV) has been recorded in nitrogen-rich steel.
