- •
Effects of interstitial impurities on grain boundary cohesion in V were studied.
- •
Interstitial C, N, B, and Fe atoms strengthen the GB cohesion.
- •
Interstitial O and S are strong embrittlers as well Si and Mo are weak embrittlers.
- •
Charge densities and structural changes provide well explanation for their effects.
