Abstract: Formation of gamma-fibre (ND//< 111 >) recrystallization texture was investigated by X-ray diffraction and Orientation Imaging Microscopy (OIM). The mechanisms of formation were broadly classified as frequency and/or size advantage -i.e. if the strengthening of texture is caused by the larger numbers and/or larger sizes of gamma-grains. Our results showed that frequency advantage of gamma-grains (through preferred nucleation of orientations with higher stored energies) was the governing mechanism. A simple scheme of preferred nucleation and deformed band coarsening proved adequate to explain developments in the global texture - both at different annealing temperatures and during different stages of recrystallization. Three factors were identified to explain/estimate the recrystallization texture: 1)lambda(i) (separation of i type deformed bands), 2)d(i) (average size of i recrystallized grain) and 3)N-i (nucleation factor of i, defined as the number of i grains per deformed i band - as measured/estimated along normal direction). The final recrystallized area fraction can be predicted as: A(i) = (N(i)d(i))/lambda(i). An effort was also made to test this simple geometric approach.
