Image Description: Fatigue failure originating at the internal corner of a keyway in a steel shaft. Fatigue failures occur under cyclic loading conditions, and cracks most often originate at a local geometric feature at the component surface (such as an edge or corner, a surface scratch or flaw, or a corrosion pit).  Using fractographic features to identify the crack origin site is critical in determining the cause of a fatigue failure. #metallurgy #metallography #failureanalysis #hardnesstesting #samplepreparation #materialscience #materialverification #materialsanalysis #oxideanalysis #fractography #chemicalcomposition #microstructuralanalysis #boilertubes #steamturbines #powerplants #dissimilarmetalwelds #whydothingsbreak #hightemperaturealloys #powerpiping #creepdamage #stresscorrosioncracking #tubefailures
