Series: ASM Failure Analysis Case Histories
Publisher: ASM International
Published: 01 June 2019
DOI: 10.31399/asm.fach.power.c9001602
EISBN: 978-1-62708-229-7
...Abstract Abstract This article presents a failure analysis of 37.5 mW gas turbine third stage buckets made of Udimet 500 superalloy. The buckets experienced repetitive integral tip shroud fractures assisted by a low temperature (type II) hot corrosion. A detailed analysis was carried out...

... strain range. Systems to which this model would be likely to apply would be those that have a stable precipitate structure (i.e., low mismatch between matrix and precipitate) and that are prone to damage by oxidation of grain boundaries. Examples would be Waspaloy, a disk alloy, and Udimet 500...
