Plasma-Material Interaction Data Set 17

Diffusivity of T in Steel

$$ D = D_0 \exp\left(-\frac{E_\mathrm{d}}{k_\mathrm{B}T}\right) $$

[In the above formula, the Boltzmann constant is expressed in \(\mathrm{eV\,K^{-1}}\).]

Comment

Data from Table 3.1 of Dolan and Anderl, who obtained it from Shan et al.
