Conclusions
-
1.
Primary recrystallization over the section of sheet semiproducts is unequal: in the surface layers of sheet it proceeds with less intensity than in deep-laying layers.
-
2.
To increase the dimensional stability of sheet materials, recrystallization annealing should be extended until primary recrystallization in the surface layers is completed.
-
3.
For the nondestructive layerwise investigation of primary recrystallization in metallic materials it is recommended to use the x-ray diffraction method.
