Abstract Scope |
In Ti alloys, hot working is used to weaken the (micro-)texture, whereas in Zr alloys a strong texture is often desired. During hot working, the texture in these materials evolves through the simultaneous action of deformation, annealing and phase transformation. Here we present an overview of recent complementary work on the texture of hot deformed Zr and Ti alloys. Hot rolling produces a characteristic transverse basal texture in alpha and a strong rotated cube texture in beta. In uniaxial compression a cube fibre develops in beta, which is stronger in the alpha+beta regime than above the transus temperature, suggesting it is enhanced by the presence of alpha. The interaction between alpha and beta phases was studied using crystal plasticity finite element modelling. For particular alpha variants, its presence helps stabilize the cube-related components. The implication of this interaction for the development of texture in forgings is discussed. |
