Abstract
Fatigue failure is one of the most common fracture modes of structural materials in the industrial field. The study of material fatigue mechanisms and methods for predicting fatigue life has always been of significant interest to researchers due to the abrupt and catastrophic failure mode. In recent decades, the performance and functionality of scanning electron microscopy (SEM) have been continuously improved and expanded. Based on this, the development of in situ fatigue testing in SEM has been rapidly developed. This technology plays a crucial role in providing insights into the deformation behavior of materials under fatigue. Keeping this in view, a comprehensive review of the development and application methods of in situ SEM fatigue testing technology is provided here. The development of in situ SEM fatigue testing devices is provided in brief overview, and the application and research progress of this technology in some representative metal structural materials (nickel-based single-crystal superalloys, steel, aluminum alloys and additive manufacturing materials) are analyzed in detail. Moreover, the perspectives on evaluating fatigue damage, particularly about small cracks and the plastic accumulations fatigue behavior, are presented in this study, utilizing the latest advancements in in situ SEM fatigue testing. Remarks about the present and outlook for future work to be done are then provided.
疲劳破坏是工业领域结构材料最常见的断裂模式之一。由于疲劳失效模式具有突发性和灾难性,研究材料的疲劳机理和预测疲劳寿命的方法一直是研究人员的重要兴趣所在。近几十年来,扫描电子显微镜(SEM)的性能和功能不断得到改进和扩展。在此基础上,扫描电子显微镜原位疲劳测试得到了快速发展。这项技术在深入了解材料在疲劳状态下的变形行为方面发挥着至关重要的作用。有鉴于此,本文对 SEM 原位疲劳测试技术的发展和应用方法进行了全面综述。简要介绍了原位扫描电镜疲劳测试设备的发展,并详细分析了该技术在一些代表性金属结构材料(镍基单晶超合金、钢、铝合金和增材制造材料)中的应用和研究进展。此外,本研究还介绍了利用 SEM 原位疲劳测试的最新进展评估疲劳损伤,特别是小裂纹和塑性累积疲劳行为的前景。随后还对当前工作和未来工作进行了展望。
