Abstract
- This article focuses on research into thermal shock fatigue resistance and oxidation resistance of as-cast ferritic nodular iron. The results show that the number of cycles required to crack nodular iron under the action of thermal stress is significantly higher than that of grey cast iron, and the rate at which cracks spread is lower compared with that of grey cast iron. When graphite is transformed from flakes into nodules, its decreased connectivity impedes the flow of oxygen during oxidization, thereby improving its oxidation resistance.
