Low Temperature Volume and Dislocation Diffusion of Homovalent Impurities in Tungsten

Diffusion and solubility of Cr in WC

“…As reported in literature activation energies for metal diffusion should be substantially larger. An example is given by Klotsman et al [13] where diffusion of chromium and However, the low activation energy is compensated by a very low D 0 so that the complete set of data is capable of estimating diffusion of Cr in WC. Such estimation is done in the next section for the Cr uptake of WC powders, assumed as ideal spherical particles.…”
