Failure Analysis of a Hydraulic Turbine Shaft

Source

A complete analysis was carried out on a hydraulic turbine shaft in order to determine the origin and causes of existing cracks. A chronological scenario of crack system creation was advanced and was confirmed by macroscopic and microscopic observations of fracture surfaces and material structure. Friction welding, occurring between shaft and sleeve, was found to be the origin of the first crack system, which in turn was responsible for the creation of others.
