“…than in Fe, which evidences the smallness of the migration volume of bi-interstitials in Fe compared to V. Most likely, this is due to the fact that the crowdion mechanism of diffusion significantly contributes to the diffusion of a bi-interstitial in Fe, in contrast to V [13]. For Fe and V, is fulfilled within the calculated error margins at all values of T and ε 1 .…”

“…We have earlier obtained the diffusion characteristics of bi-interstitials in Fe and V in the absence of external elastic fields by the MD method [12,13]. In this study, the dependences of the diffusion characteristics of bi-interstitials on the value of the uniform elastic deformation of the crystal (in the range from -1 to + 1%) for strained states V 1 , V 2 , and V 4 were calculated by the MD method for bcc metals Fe (350-800 K) and V (350-600 K).…”
