  The NIFS-grade vanadium made it possible to systematically investigate the nitrogen effects at low oxygen levels. The purpose of this study is to investigate the effects of nitrogen and oxygen on recovery and recrystallization of vanadium after work hardening using high-purity metal vanadium singly doped with nitrogen or by: Download PDF: Sorry, we are unable to provide the full text but you may find it at the following location(s): (external link) http Author: E.

Dynamic Recrystallization Behavior of Vanadium Micro-alloyed Forging Medium Carbon Steel Abstract: The dynamical recrystallization of Micro-alloyed forging steel was investigated at deformation temperatures of °C and strain rates of –5 s–1 on a Gleeble dynamic thermo-mechanical simulator.   Torsion tests were conducted to study the static recrystallization of three microalloyed steels manufactured by electroslag remelting (ESR) with different percentages of vanadium, %. % and %, respectively, and approximately equal percentages of the other alloyforming elements. It was seen that, in contrast to niobium, dissolved vanadium has no influence on the .

The effect of matrix recrystallization on the morphology and crystallography of B1-type vanadium carbide (VC) formed in austenite (γ) was studied in an Fe–12Mn–V–C (mass%) alloy by transmission electron microscopy. Dynamic recrystallization-time-temperature (RTT) curves were developed from the flow curves at × 10 −3 and × 10 −2 s −1. At the higher strain rate, only the solute retardation of recrystallization was detected for the vanadium, Nb-V, Nb Mn and No-Mo steels.   Once again, recrystallization is initiated earliest in the plain carbon steel. Vanadium, even at these longer times, retards recrystallization by only a small ratio, which does not vary appreciably (on a log-time base) over the experimental temperature range. Relative to the plain carbon steel, the addition of % Nb pro- AKBEN t'l ni. The nature of dynamic recrystallization stress-strain curves was studied following an increase or decrease in strain rate after deformation into the steady state region. For this purpose, a vanadium microalloyed steel was hot compressed at constant true strain rates of × 10 −5 s −1 to × 10 −2 s −1 at a testing temperature of.
