The objective of this work was to determine the relationship between texture development and anisotropy of shape memory properties. A commercial Ti-45Ni-5Cu (at.%) shape memory alloy was selected. Textures were developed by controlling rolling parameters, such as rolling temperature, intermediate annealing temperature, thickness reduction and annealing temperature. The anisotropy of shape memory properties, in particular the transformation strain, was measured by tensile and thermal cyclic testing under constant load. Texture measurements were made after rolling, tensile testing and after thermal cyclic testing. The anisotropy of shape memory alloys was then related to the textures obtained based on the experimental results as well as theoretical modelling.
