Impurity's fe
WitrynaThe partial density of states (PDOS) of impurity atoms and Fe atoms is described in Figure 1i−k. It can be seen that the 1s orbital of the H atom and the 3d orbital of the Fe atom hardly overlap, which indicates that the interaction between the H atom and Fe atom is very small. The 2p orbitals of both O and Witryna16 kwi 2010 · Several clusters of fine precipitates of light-colored features, identified to be Fe-rich intermetallics, were observed within the microstructure both before and after the filtration process. Fe has unlimited solubility in molten aluminum, but in solid aluminum, it is soluble only up to 0.04 pct.

Witrynaimpurity is shown in Figure 2 versus impurity content. At low impurity concentration (x = 0.01 to x = 0.03 for Fe and to x = 0.02 for Co) we got a negligible cell magnetization. At such low concentrations Co and Fe are non-magnetic. The average magnetization of im-purities versus impurity content is shown in Figure 3. As was discussed in our ... 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
