The texture development of silver single crystals and polycrystalline high purity silver rend a series of Ni-Co 8lloys was examined, immediately 8ft.er rolling 8nd 8ftor various annealing treatments. X-ray diffmction esd electron-microscopical observations showed that the development of the {841}(447) + (310~991) + {,352i}(246) recrystallis8tion texture can be expleined by the inverse Rowland trans-form&ion as the prinmry nucliation mechanism followed by recrystellisation twinning and growth selection of secondary twins. DEVELOPPEMENT DE TEXTURES DE RECRISTALLISATION DANS LES METAUX C.F.C.

La diffmction de rayons-X et les observations au microscope Blectronique ont montre que l'on pouvait expliquer le developpement de la texture de recristallisation {841)(447) + {310}(991) + {862}(246) par la trensformation de Rowland inverse comme mecanisme de germination primaire suivi d'un maclage de recristellisetion et d'une croissrtnce s6lective de mecles secondeires.

Abstract-After an 80.9"" plane-strain deformation of Ag crystals with an initial orientation of ~ilO) [~l] and (iIO)[ll?] both orientations proved to be stable. The spread in orientation was no more than about 10' from the initial orientation. The new orientations resulting from the recrvstallization process can reasonably be explained by a continuous array of tu-ins. Both with X-ray techniques and by means of electron microscopy orientations within 5' of those of ta-ins up to the fourth order have been observed. None of these twins possessed 3 30--10' orientation relationship around a common (11 l} axis with the deformed matrix.
