The present paper describes experiments set up to show that the frequency of annealing twills ill recrystallized metals depends on the orientation relationship between growing crystal and matrix texture. It is shown in particular that growth of a crystal in a "bent" strip, in which the abovementione

β¦ Synopsis
By the use of transmission electron microscopy of thin copper foils, direct evidence has been found of twinning dislocations and of their association with recrystallization twins. Although several properties of recrystallization twins can be explained on the basis of these dislocations, the origin of the twins is still a matter of speculation.

PAR MICROSCOPIE ELECTRONIQUE DES MACLES DE RECRISTALLISATION DANS LE CUIVRE Par observation dire&e au microscope blectronique, de feuilles minces de cuivre, les auteurs mettent en Evidence les dislocations de macles et montrent leur association avec les macles de recristallisation. Bien que la plupart des propr%t&s de ces dernibres puissent %re expliquees sur la base des dislocations observi?es, l'origine des macles n'est pas encore bien dkterminke. ELEKTR,ONENMIKROSKOPISCHE UNTERSUCHUSG T'ON REKRISTALLISATIOXS-ZWILLINGEN IN KCPFER Diinne Kupferfolien wurden irn Elektronenmikroskop durchstrahlt. Dabei wurden direkte Beweise fiir die Existenz van Zwillingsversetzungen und ihren Zusammenhang mit Rekristallisationszwillingen gefunden. Obwohl sich verschiedene Eigenschaften der Rekristallisationszwillinge mit Hilfe dieser Versetzungen erkliiren lassen, ist doch der Ursprung der Zwillinge noch nicht ganz aufgekliirt. t European Research Association, s.a.,
