Electronic Thesis and Dissertation Repository
Constant-load pyramidal indentation creep tests and high precision micro-indentation strain rate change tests were performed to assess the effect of indentation depth, irradiation damage and temperature on the mechanical anisotropy and local plastic deformation parameters of the Zr-2.5%Nb CANDU pressure tube material. Polished samples aligned normal to the transverse (TN), axial (AN) and radial (RN) directions of the pressure tube were irradiated with 8.5 MeV Zr+ ions to simulate the effect of neutron irradiation. Constant-load pyramidal indentation creep tests performed at 25ºC show that the average indentation stress increases with decreasing indentation depth and increasing levels of irradiation. The …
