摘要

The effects of dispersoids present prior to softening vs. concurrent precipitation on thernrecrystallization process after cold rolling have been considered. The materials containingrna large supersaturation of Mn and consequently a large precipitation potential, are stronglyrnaffected by precipitation taking place concurrent to the softening processes. Further, it hasrnbeen shown that the recrystallized grain structure and texture is relatively unaffected byrnthe dispersoids present prior to annealing unless the density becomes very high, and inrnthese cases the effect becomes similar to the effects caused by concurrent precipitation,rnbut weaker. In these extreme cases of precipitation, both nucleation and growth of thernrecrystallized grains are retarded due to the dispersoids, giving an inhomogeneous,rncoarse, recrystallized grain structure and a strengthening of the texture.
