| Abstract: | A Zircaloy-4 alloy with Widmanst?tten-Basketweave microstructure has been used to study the deformation behavior at the grain
level. The evolution of internal strain and bulk texture is investigated using neutron diffraction and conventional microscopic
techniques. The macroscopic behavior and intergranular strain development, parallel and perpendicular to the loading direction,
were measured in situ during uniaxial tensile loading. It was observed that twinning plays a major role in both microstructural changes and polycrystalline
plasticity. |
