摘要：
The thermo-mechanical fatigue (TMF) behavior and the relevant microstructural evolution of the single crystal nickel-based superalloy DD8 were investigated. In-phase TMF lives were much shorter than those of out-of-phase TMF. The mechanism of TMF damage is discussed based on the microstructural evolution during TMF. (C) 2003 Acta Materialia Inc.
