“Conjugate Channeling” Effect in Dislocation Core Diffusion: Carbon Transport in Dislocated BCC Iron

Figure 1

Illustration of conjugate channeling effect in dislocation core diffusion.

Black arrows indicate the carbon diffusion path through bulk lattice (O-site) along and black dots indicate the O-site along the path. Red arrows indicate the carbon diffusion path through dislocation core along . is the maximum dislocation core length which can be dragged by single carbon atom (See text for details). The dislocation loop is located between th and +1th plane as shown in upper right figure. Lower right figure show the relation between conjugate diffusion vector c and Burgers vector b.
