Abstract
The cyclic deformation and fatigue behaviour under thermo-mechanical load of the 3rd generation γ-TiAl alloy TNB-V5 are evaluated. Strain controlled thermo-mechanical and isothermal fatigue tests were carried out with two different strain ranges, different temperature–strain cycles and different temperature ranges from 400 °C to 800 °C. Cyclic deformation curves, stress–strain hysteresis loops and fatigue lives of the tests are presented. The fatigue lives were well described by the Smith–Watson–Topper damage parameter.
