Abstract
The indentation method was found to be a suitable method for determination of the creep properties of small weld joints of nuclear fuel pins. The activation energy for the creep for TIG welded sample was found to be ~40% more than the base metal. Both base metal and resistance-welded specimens have the same activation energy for creep and match with self-diffusion values of Zricaloy. Since the value of n estimated in the study is in the range of 5.5-7.6 the most probable mechanism is dislocation creep in the power-law regime.
