Vanadium and niobium microalloying to increase strength of high-carbon wire steels

$15.00

In order to investigate the effect of V, Nb, and N additions on the strength of eutectoid steels, laboratory heats were prepared and continuous cooling experiments were conducted using a Gleeble® 3500 thermomechanical simulator. V strengthening effects were observed in all microalloyed steels, and maximum strengthening was observed in the V+N steel. The V+Nb steel was found to have the greatest refinement of colony size and ILS, and subsequently higher hardness among the test alloys.
