Witryna15 sie 2014 · The impurity diffusion coefficient of Fe in Cr evaluated using the current forward-simulation method is 1.1 × 10 −16 m 2 /s at 1100 °C, which is very close to the literature values of 1.1 × 10 −16 m 2 /s [20] and 4.0 × 10 −17 m 2 /s [21] reported at the same temperature, as shown by the green arrows on the left-hand side of Fig. 2 (c). Witrynaisfied for impurities randomly distributed on the regular iron sites [6–8]. Therefore one can attempt to separate volume and conduc-tion band (chemical bonds) modification effects due to addition of impurity provided the volume effect is calculated by using ab initio methods for the pure iron. In order to do so one has to calculate the
WitrynaImpurities are separated as the primary, who were already in the primary metal, and secondary, which have been introduced or formed in subsequent stages of treatment of the alloy. Iron, like silicon, It belongs to a group of impurities, which have the highest content of the alloy. Abstract. There is an ongoing debate on elucidating the actual role of Fe impurities in alkaline water electrolysis, acting either as reactivity mediators or as co-catalysts through synergistic interaction with the main catalyst material.
