Effect of mode of deformation by rolling on texture evolution and yield locus anisotropy in a multifunctional β titanium alloy

Present work describes the evolution of texture during different modes of deformation by cold rolling of a Gum metal or multifunctional beta titanium alloy. The cold rolled materials exhibit the presence of beta and small amount of stress induced martensitic (alpha '') phases. The development of texture has been explained in terms of alpha and gamma fibres. The effect of different modes of rolling results in different patterns of changes in the intensities of texture components in the alpha fibre. The overall intensity of gamma fibre reduces with increase in cold rolling reduction in TCR, MCR and CR specimens although distribution of intensities is different in each case. Texture hardening occurs with increase in rolling reductions in all the modes of rolling. The extent of anisotropy is maximum in MCR while it is minimum in CR specimens. (C) 2012 Elsevier B.V.
