A general review of the texture characteristics in hexagonal close-packed metals is given with special reference to zircaloy tubing used in the nuclear industry. Conclusions concerning the deformation forces and their effect on the resulting deformation mechanisms are detailed. It is shown that the texture formation is governed by the material flow, which for tube reductions is determined by the reduction in cross-section, wall thickness and diameter, and, more specifically, by the relative ratio of wall to diameter reduction. By knowing the relationship between texture formation and reduction pazameters, it is possible to tailor the texture in zircaloy tubing within the given limits, according to in-service requirements. |
