Outline of Final Research Achievements

A new testing system has been developed which enables us to apply mechanical loadings superimposed with thermal loadings to the superalloy specimens with cooling systems and thermal barrier coatings (TBCs) in a simulated combustion gas environment. Some specific thermo-mechanical fatigue (TMF) and creep tests were carried out to understand the failure features under the significant thermal gradient (TG) conditions. Special focus was also put on an inteaction between low-cycle and high-cycle fatigue (LCF/HCF) loadings. The xperimental works clearly demonstrated that some specific behaviors were got pronounced in the superalloy substrate and the TBCs under a significant TG. The additional damages were accounted when the TG was coupled with the influence of the DBTT of the bond coat. Mechanistic discussion was also made to condense these knowlege into engineering damage map for life assessment of advanced gas turbine blades subjected to more significant TG conditions.
