    Influence of the neutron irradiation on microstructure and mechanical properties of coarse and ultrafine grained Titanium Grade 2

  • Original language description

    The influence of the neutron irradiation on the microstructure and mechanical properties of commercially pure (grade 2) Ti in coarse and ultrafine-grained condition was investigated. It was found that mechanical properties of the coarse-grained (CG) was significantly affected by neutron irradiation. In particular, the yield stress increased from 643 MPa to 866 MPa at room temperature (RT), whereas the ductility decreased by more than 100%. At the temperature of 300 °C even higher difference in the mechanical properties between irradiated and non-irradiated state was observed. On the other hand, the ultrafine-grained (UFG) state is more resistant to the radiation damage. The mechanical properties did not change upon the neutron radiation at both testing temperatures. Such enhanced radiation resistance can be attributed to UFG microstructure which exhibits high value of dislocation density. Thus, new dislocations generated through neutron irradiation did not further increase the overall dislocations density of UFG state.
