Abstract

By examining thin sections and by use of the more strongly absorbed Ti Kα radiation rather than Fe Kα radiation it was found possible to obtain useful transmission Kossel patterns from iron that had been deformed 40% by rolling. Examination of the as–deformed material showed large misorientations in all the matrix grains (20–54°) and many of the grains showed deformation bands where the orientation changed rapidly (up to 15° over distances of 50 μm). On annealing the material recrystallized by strain-induced boundary migration with all the invaded grains being those with (111) parallel to the rolling plane. Only one example was found of new grain formation by mutual invasion across a deformation band, the main nucleation mode previously observed in aluminum deformed 40% by compression. The difference between the two examples appears to arise from the smaller misorientations of the deformation bands in rolled iron.
