Have a nice weekend,

Hello folks, I am having problems to find de the self-diffusion coefficients of Cr and of Nb.
Does anyone have these numbers with reference ?
Thank you a lot for your time to answer me,

Thanks arunmrao, interesting point you've raised but I was thinking about beers or gaseous beverages that are stored at ambient temperature. What is then, in your point of view, the relationship between CO2 with the ductile-brittle temperature? Thanks for giving me any more clues.
