WebSep 15, 2024 · When the disregistry is more than 12%, the nucleation effect of the heterogeneous core is poor. In Table 4, the disregistry between δ iron, TiN, and MgO is less than 6%; thus, MgO and TiN can serve as an effective core of δ iron nucleation. Furthermore, the disregistry between TiN and MgO is also less than 6%.

Webatomic disregistry across the glide plane, and the relationship between the dislocation width and the atomic interplanar separation across the glide plane. The analysis is based on the assumption that the disloca-tion core radius periodically varies during the glide of the dislocation between its consecutive equilibrium conflgurations. WebNov 26, 2024 · A screw dislocation is more complex - the Burgers vector is parallel to the dislocation line. Mixed dislocations also exist, where the Burgers vector is at some acute angle to the dislocation line. In a 2D model such as the bubble raft, only edge dislocations can exist.
