Abstract
The method of computer simulation is applied to investigate the role of cross-slip in the formation of rolling textures in f.c.c. metals and alloys. A simplified macroscopic model, static plane stress rolling, is combined with a microscopic model. Deformation is carried out stepwise for a statistically representative number of crystallites, each modelled so that normal slip, {111}〈110〉, and varying amounts of cross-slip facilitate deformation. By choosing the appropriate amount of cross-slip the complete series of f.c.c. rolling textures was obtained, including transitional brass-copper textures. Surprisingly, it was found that the range of the series is wider than was previously known: a second series starting from the copper texture was simulated. A transitional texture of this second series was found to exist in rolled and annealed aluminium, where conditions for cross-slip are extremely favourable. Finally the implications of the present findings on dislocation theory for high degrees of deformation are discussed.This publication has 17 references indexed in Scilit:
