Grain size effect on radiation tolerance of nanocrystalline Mo

Grain size effect on radiation tolerance of nanocrystalline Mo

We report a significant grain size effect on radiation tolerance of nanocrystalline Mo under He ion irradiation. Irradiation-induced dislocation loops mainly contribute to the irradiation-induced hardening of Mo films with grain size of >90nm, while few such loops in those with grain size of
