dc.description.abstractSelf-diffusion in chromium single crystals has been measured over the temperature range 1073 to 1446 K. These data, when combined with earlier measurements from this laboratory over the. range 1370—2090 K, yield a plot of lnD vs 1/T, which is straight over ten orders of magnitude in the diffusion coefficient D. The high values of the preexponential factor (1280+ 230 cm's ') and activation enthalpy (4.58+ 0.03 eV) are not readily interpreted in terms of a specific diffusion mechanism. They appear to be too high to be interpreted in terms of a monovacancy mechanism. The possible contribution of divacancies and self-interstitials are discussed.en_US
