Failure Of Turbomachinery Components.
MetadataShow full item record
The analysis of turbomachinery failures is a highly specialized field requiring a detailed understanding of superalloy metallurgy, moderate and high temperature failure mechanisms and an appreciation of the stresses, excitations and mechanical design characteristics of the various parts. Common failure mechanisms such as creep, fatigue, oxidation, corrosion, and wear are often observed, either singly or in combination, which makes the identification of the primary mode of failure more complex. To assist with the identification of service failures, a review of the principal failure mechanisms is presented along with the associated metallurgical features. In addition, a number of cases are presented to emphasize the need for a cooperative approach to failure analysis in order to translate the metallurgical information to possible mechanical/operational causes and solutions.
