摘　　要：世界已逐渐进入以物联网和智能制造为主导的工业4.0时代,特别是人工智能和大数据处理的强烈需求,微纳米尺度器件的研发制造及广泛使用的日趋活跃使得小尺度材料得到广泛关注。由于这些材料的几何尺度和微观结构尺度的约束效应,其热疲劳损伤行为与块体材料不同。同时,材料尺度由微米向纳米量级的转变也会引起损伤机制的转变,使材料表现出不同的损伤形式,产生显著的尺寸效应。本文综述了近年来国内外开展的有关金属薄膜/线的热疲劳实验方法、热疲劳损伤行为及演化和热疲劳影响因素的研究进展,探讨了微纳米尺度金属材料热疲劳的微观机制和尺寸效应,并对这一领域的研究前景进行展望。The world has gradually entered the industrial 4.0 Era, which is dominated by the Internet of Things （lOT） and intelligent manufacturing. Especially, strong requirement for artificial intelligence and big data processing, the development and preparation of micro/nano electronic devices is becoming increasingly active, and much more concerns have been attracted to small-scale materials. Because of the constraint effect of geometric and microstructural dimensions of these materials, the thermal fatigue damage behavior is different from that of the bulk counterparts. At the same time, the change of the mate- rial scale from microns to nanometers also results in the transformation of the deformation mechanism, so that the materials exhibit different damage behaviors and significant size effects. In this paper, thermal fatigue testing methods, thermal fatigue damage and evolution, and the factors influencing thermal fa- tigue properties of metal film/line are reviewed, the corresponding mechanism of thermal fatigue and the size effect of the micro/nano-scale metals are discussed. The prospective research of this field in the fu-ture is addressed.
