uranium was developed. It is based on a stress deformation of the imperfect crystals from the beta -- alpha phase transformation, followed by a high temperature anneal above the alpha phase. Depending on the orientation of the original crystal, deformation occurs by slip, twinning, or deformation bands. Annealing gives perfect recrystallization crystals, whose orientation has a direct relationship with that of the original crystals. During the recrystallization there are some crystallographic characteristics of the deformation mechanism. The (0 0 1), which is the rotation axis allowing the formation of the deformation bands, is preserved during recrystallization. In the case of deformation 5y twinning, the recrystallized grains show less clearly marked orientation relationships, but the growth of larger crystals is facilitated. (tr-auth)
