FEASIBILITY OF THIN-FILM ELECTRON MICROSCOPY FOR STUDY OF FINE DEFECT STRUCTURE IN STEEL AFTER LOW CYCLE FATIGUE

Application of recent developments in thin-film transmission electron microscopy to specimens of ABS Class-C steel fractured by low cycle fatigue demonstrates that changes in fine defect structure can be clearly observed. It is concluded that this method is capable of revealing much information about the extent, magnitude and nature of low cycle fatigue damage in mild steel.
