摘要

研究人员开发了一种新颖的条件生成对抗网络（cGAN）与改进的电化学-机械（E-C-M）模型的集成方法，用于计算高温水中的局部电化学并评估应力腐蚀开裂（SCC）的裂纹起始特性。结果表明混合方法具有卓越的准确性、计算效率和强大的概括能力。为了验证和优化用于计算高温水中奥氏体不锈钢（ASS）应力诱导腐蚀行为的 E-C-M 模型，进行了高温电化学测试。SCC 引发试验结果证实了具有双相结构的 ASS 上预测的腐蚀电流分布。

Conditional generative adversarial network-based predictive method for crack initiation in a dual-phase austenite stainless weld

A novel integration approach of a conditional generative adversarial network (cGAN) with an improved electro-chemo-mechanical (E−C−M) model was developed to calculate the localised electrochemistry and evaluate the stress corrosion cracking (SCC) crack initiation properties in high-temperature water. The results demonstrate the superior accuracy, computational efficiency and robust generalisation capabilities of the hybrid method. High-temperature electrochemical tests were conducted to validate and optimize the E−C−M model for calculating the stress induced corrosion behavior of austenite stainless steel (ASS) in high-temperature water. The SCC initiation test results corroborate the predicted corrosion current distribution on ASS with a dual-phase structure.
