摘要：

Aluminum alloy RR 58 (AA 2618) was viewed during exposure to cyclic loading, which is applied using a load frame inserted into a scanning electron microscope. Thus, observation of surface interactions of the material microstructure with a propagating crack is feasible. Photomicrographs and (for the purposes of analysis and presentation) dynamic, real-time video-recordings used to document the processes are displayed and the nature of the observations presented in relation to existing physical understanding of fatigue.
