摘要

The development of a fatigue in situ Scanning Electron Microscope (SEM), designedto monitor the growth of short cracks on high performance materials at elevated temperatures, is described. Its use is demonstrated with respect to the formation and growth of short cracks in Waspaloy at 25 and 500 C subject to fatigue at R = 0.1. Short crack growth was found to occur at greater rates at 500 C in comparison to 25 C. The difference was attributed to a change in slip mode resulting in a change from highly faceted growth to a more homogeneous growth.
