π₯ Exploring Synergistic Damage in SiC Under Extreme Conditions π₯
This groundbreaking study investigates the synergistic effects of He ion irradiation and FLiNaK molten salt corrosion on SiC at 750Β°C. Over 166 hours, key structural changes were observed, shedding light on material behavior under high-stress environments.
Key findings:
β
Si denudation forms a carbon-rich layer, with graphite structures characterized using TEM.
β
Ni impurities in the molten salt preferentially react with Si-Si bonds, accelerating corrosion.
β
He bubbles near C-rich layers decrease in density but increase in size, driven by vacancies from Si loss.
This research offers valuable insights into the stability and durability of nuclear materials under extreme conditions.
