摘　　要：在高价值应用中,针对尺寸小于100μm的小尺寸缺陷的检测可靠性对于关键部件的结构安全至关重要。早期缺陷通常可以修复,通过延长组件的使用寿命和重复使用,为循环经济和可持续性做出贡献。在运行过程中,小规模缺陷通常是由蠕变、疲劳、热循环、环境破坏或这些多物理载荷条件的任何组合引起的。无损检测技术与机器学习和先进的后处理信号算法相结合,提供了可区分的高检测精度和分辨率。In high-value applications,the reliability of detection of small size defects less than 100μm is critical to the structural safety of critical components.Early defects can often be fixed,contributing to the circular economy and sustainability by extending the useful life and reuse of components.During operation,small-scale defects are usually caused by creep,fatigue,thermal cycling,environmental damage,or any combination of these multi-physical load conditions.NDT technology,combined with machine learning and advanced post-processing signal algorithms,provides distinguishable high detection accuracy and resolution.
