摘要: Crystal orientation and mechanical properties of Zircaloy-4 (Zr-4) alloy cladding tube manufactured by cold Pilger rolling and annealing were systematically investigated. Electron Back-Scattered Diffraction (EBSD) analysis showed that grains, which were fully recrystallized in alpha phase, were strongly oriented with their c axis parallel to the tangential direction (TD) of the tube and, meanwhile, their normal direction of {11 (2) over bar0(}alpha) planes parallel to the axial direction (AD). Compression tests carried out along three loading directions (TD-0 degrees, TD-45 degrees and AD, respectively) at room temperature revealed that the Zr-4 alloy tube exhibit strong yielding anisotropy: TD-0 degrees > TD-45 degrees > AD. Meanwhile, the alloy exhibited strain rate hardening effect, since the yield strength increased with the growing strain rate. The relationship between texture and yielding anisotropy of the Zr-4 alloy tube was further discussed based on Schmid factor theory. The Schmid factor values for basal, prismatic and pyramidal < a > slip systems, which were three important yielding mechanisms in Zr-4 alloy during the compression, were calculated depending on the geometric relationship between loading directions and crystal-lography. Calculation results revealed that there was an inverse relationship between Schmid factor value for slip modes and the compression yield strength of the Zr-4 alloy.
