Abstract：Vanadium has obvious effects on the microstructure, mechanical properties and thermo-stability of high carbon steel wire. In high carbon steel, vanadium mostly exists in cementites to reinforce them. The addition of vanadium is beneficial to the refinement of pearlite lamella spacing, and can increase the thermo-stability of cementites, so as to restrain cementite dissolution during steel wire drawing. However, fragmentation occurs to cementites with rich vanadium under a larger drawing strain, and steel wire spheroidization would aggravate during galvanizing, which, compared to non-V-alloyed steel wire, leads to the obvious decline of torsional property no matter V-alloyed steel wire is galvanized or not.
