Abstract
Role of Sn on the deformation mechanisms of Zr was investigated using in situ neutron diffraction and complementary electron microscopy techniques. Binary Zr-Sn alloys having fully recrystallized microstructure and typical rolling texture were subjected to in situ loading and diffraction experiments along the rolling direction of the sample. Significant twinning activity was observed and the twins were observed to be {101 ̅2}〈101 ̅1〉 type tensile twins. Critical stress for the twin nucleation and the extent of twinning were found to be strongly influenced by the Sn content. Critical plastic strain for the nucleation of twining, however, was observed to be weakly dependent on the Sn content. Results indicate significant plastic slip activity to be a necessary condition for the onset of twinning. http://mc04.manuscriptcentral.com/astm-stp STP: Selected Technical Papers
