摘要
本文利用正电子湮没技术研究,Fe-V稀合金渗N后出现的V-N-空位复合结构。测定了这种复合结构的正电子湮没寿命值和估算了空位形成能。为解释Fe-V合金渗N后V的增强扩散机制提供实验依据。
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.
