Abstract
The fatigue behavior at heat affected zone, HAZ, of TIG zirconium weldment in boiling nitric acid has been studied to evaluate with respect to the reliability of commercial nuclear fuel reprocessing equipments made of zirconium. The crack growth rate was measured as a function of the stress intensity factor both in boiling nitric acid and in air at room temperature. The fracture morphology was examined with a scanning electron microscope. The crack growth rate in boiling nitric acid was ten times faster than that in air at room temperature. The fracture surface formed in nitric acid showed both the brittle striation and quasi-cleavage type facet. Comparing with same testing results of base metal, these results of weld metal and the HAZ showed the SCC susceptibility similar to that of base metal. (author)
