Isotope effect in niobium self-diffusion
Journal Article

· Phys. Rev. B: Condens. Matter; (United States)
Measurements of the isotope effect in niobium self-diffusion have been made over the temperature range 1900 /sup 0/C to near the melting point (2468 /sup 0/C). The measurements were made by simultaneous diffusion of /sup 95/Nb and /sup 92/Nb isotopes from a thin surface layer and subsequent sectioning. The ratio of /sup 92/Nb to /sup 95/Nb in each section was determined using a well-type Ge(Li) detector of high efficiency. The low values of the measured isotope effect are similar to other bcc metals (Na, ..cap alpha..- and delta-Fe, Cr, and ..beta..-Zr); however, the temperature dependence is different.
