The vanadium-nitrogen-vacancy complexes appearing in the dilute Fe-V alloys doped with nitrogen have been studied using positron annihilation technique. The positron lifetime and formation enthalpy of the complex were estimated. The results provide an experimental evidence to explain the enhanced diffusion of vanadium in dilute Fe-V-N alloys.
