New theory of the FCC rolling texture transition

Abstract

Deformation banding is observed to be an important deformation mode and its inclusion into texture modelling in a Taylor framework produces textures in which S, C and B coexist. This result is based on octahedral slip and does not require any inhomogeneous deformation mechanism other than deformation banding. Extensive SEM and TEM microstructural investigation of α brass showed that S, B and G are present in significant untwinned quantities in the rolling range 60-85%. It is concluded that these are formed by normal slip plus deformation banding, in an identical manner to that in copper. The major difference in textures between high and low SFE metals arise, therefore, from the behaviour of C.
