RELATIONSHIP BETWEEN ROLLING TEXTURES AND SHEAR TEXTURES IN FCC AND BCC METALS

The rolling and shear textures of aluminium (fc.c.) and Fe-16% Cr (b.c.c.) have been compared. First a 90-degrees rotation relationship about the transverse direction was found experimentally between the stable orientations of the rolling textures and the shear textures. This was explained with the symmetry of the glide systems and the orientation relationship between both coordinate systems. Second for both kinds of deformation namely rolling and shear a 90-degrees rotation relationship about the transverse direction was also found between the stable b.c.c. and fc.c. orientations. This was explained with the Taylor theory and the Sachs model making use of the orientation relationship between fc.c. and b.c.c. glide systems.
