Twinning deformation at room temperature of fast-neutron irradiated titanium

Abstract Effect of the neutron irradiation on the twinning deformation has been studied with unirradiated and irradiated titanium. An optical microscope was used to reveal the deformation modes at different strains and to obtain the twin volume fraction Vt and the twin density Nt as a function of strain. The value of Vt and Nt are larger in the irradiated specimens. A detailed study shows that the nucleation of twins is remarkably enhanced by irradiation, in agreement with the observation by transmission electron microscope. The twins are nearly all of {1012} system.
