“…Wang and Bainbridge [5] conducted low rate tensile experiments on high purity polycrystalline vanadium and concluded that the Peierls mechanism was dominant below about 200K while dislocation-interstitial interactions were dominant at high temperatures. The important role of interstitial impurities in vanadium (a characteristic of BCC Article published online by EDP Sciences and available at http://dx.doi.org/10.1051/jp4:1997396 JOURNAL DE PHYSIQUE IV materials) has been documented by Vorob'eva and Gulyaev [8], Kainuma et al [9] and others [6, 10, 1 11.…”
