Aluminum foils, cold-worked by rolling to a reduction degree of 98%, are further reduced in thickness by electrolytic polishing. After rolling the metal has a structure formed of small blocks with dimensions of approximately one micron. If the metal is annealed before the electrolytic polishing, the structure is more perfect. If the sample is annealed after the polishing, the perfecting of the structure is observed, but the anneal temperature must be raised from 120 to 2504DEC. No enlargement of the blocks were detected in the samples annealed after polishing. For very high purity aluminum, obtained by zone melting, recrystallization occurs in thickness 30 times less than the thickness at which recrystallization occurs in aluminum refined by double electrolysis.
