| Abstract Scope |
Crystallographic texture generated during fabrication of pressure tubes and in service they results in anisotropic deformation.The dual phase high strength Zr-Excel alloy pressure-tube has been suggested for use in the CANDU Generation-IV Super Critical Water Reactor(SCWR) design.The conceptual design of SCWR has significant constraint at two ends than the existing CANDU design; hence the tube must show very low elongation in-service.Thus a more isotropic texture requires to develop for SCWR.In experimental, samples cut from as-extruded excel tube and at a range of temperature heat-treated within α+β and β phase fields.Due to the various possible variants selection during transformation from α-β-αa randomization of texture is possible during heat treatment.The modified texture results from heat-treatment has been determined by neutron diffraction.A relationship has been determined between heat treatment and resolved basal plane normal fractions (fA, fR and fT), demonstrating the degree of randomization of texture obtained by heat treatment. |
