High Temperature Low Cycle Fatigue Properties and Failure Mechanism of a TiAl Alloy

High Temperature Low Cycle Fatigue Properties and Failure Mechanism of a TiAl Alloy

Total strain range controlled low cycle fatigue (LCF) experiments were conducted at 750 ℃ to investigate the effects of the duplex and fully lamellar microstructure on fatigue behavior and life of a TiAl alloy, and the total strain range-life equation was employed to predict LCF life of the alloy. T...
