Orientation of recrystallized grains in strained aluminum single crystals

摘要: Abstract Artificially nucleated crystals were grown in strained aluminum single by cutting them at one end with pliers and then subjecting to recrystallization heating. An overwhelming majority of the new showed an orientation characterized a 40° rotation around [111] axis relative old matrix. Recrystallization always started cut many fine grains. After further heating most these grains disappeared only few large left. They grew into deformed matrix finally occupied full diameter wire. Laue Debye-Scherrer X-ray photographs that early stage distributed random, while crystal obtained usually was rotation. This indicates preferred final originates growth selection. The preference for rather than other 〈111〉 axes may be caused either plastic deformation matrix, or fact boundary between two is pure tilt if both have common axis.
