The P was found to segregate preferentiallyalong dislocation line during recovery annealing. The P-riched dislocation densingregion, the P-depleted region and the sub-grain-like boundary are thus formed. Thenuclei grow preferentially during recrystallization in such region that the P segre-gation is more evident and the residual strain by dislocation densing increases tolarge extent. After recrystallized, the P segregates along grain boundaries and makesfine grain of the alloys.
