A new generation of models for predicting corrosion damage in stainless steel

预测材料退化和腐蚀造成的局部损伤是一个长期存在的科学挑战，具有重要的技术意义。从干存罐的大气应力腐蚀破裂到水堆部件的老化退化。现在有机会首次开发一代模型，这些模型可以明确地解决潜在的物理问题，并在合理的尺度上提供可靠的预测。这是由于复杂的多物理模型和用于跟踪复杂界面演变的新相场算法的发展而成为可能的。

Predicting material degradation and localised damage due to corrosion is a longstanding scientific challenge with important technological implications. From atmospheric stress corrosion cracking of dry store canisters to ageing degradation of water reactor components. There is an opportunity now to develop, for the first time, a generation of models that can explicitly resolve the underlying physics and deliver reliable predictions over sensible scales. This is made possible by the development of sophisticated multi-physics models and new phase field algorithms for tracking the evolution of complex interfaces.
