Abstract
An austenitic iron-nickel-chromium-molybdenum steel, known as Alloy 718 (N07718), has been investigated for its corrosion resistance in an aqueous environment relevant to the sulfur-iodine (S-I) process, proposed to generate hydrogen using nuclear heat. The slow-strain-rate (SSR) testing method was used to evaluate the cracking susceptibility of this alloy at ambient and elevated temperatures. A strain rate of 3.3 × 10−6 sec−1 was used in these tests. The localized corrosion behavior of this alloy was also evaluated by the cyclic potentiodynamic polarization technique. Further, the fracture morphology of the specimens used in SSR testing was determined by scanning electron microscopy.
