This paper reviews the thermomechanical fatigue (TMF) studies performed on various titanium aluminide (TiAl) alloys during the last decade in the research group of one of the authors (H.-J. Christ). The investigated alloys are Ti–47Al–2Mn–2Nb (

In this study the stress-dependence of the elastic modulus at elevated temperatures during fully-reversed low cycle fatigue of the titanium alloy Ti6242 is examined. The change of the elastic properties with stress manifests itself in a crescent-like

Although there exists a good understanding of dislocation glide mechanisms during fatigue of titanium aluminides, [1] fatigue life prediction remains a crucial issue because of the low amount of macroscopic plastic strain and the existence of microst

The micromechanisms controlling low cycle fatigue of a Nb-bearing TiAl alloy (TNB-V2) have been characterized by conventional and high-resolution transmission electron microscopy. Fully reversed isothermal tests were performed under strain control at

TiAl is supposed to substitute Ni or Ti alloys in energy conversion systems, such as aero engines. These components are subjected to thermomechanical fatigue (TMF), whereas this mechanical behaviour may substantially differ from isothermal low cycle

Ti6242 is the workhorse of high-temperature Ti-alloys in the high pressure compressor of aero engines. In this study the influence on isothermal fatigue of different load controls, i.e. stress, total strain and plastic strain control at different tem

LCF and TMF tests were conducted on Ti6242 and on the intermetallic TiAl alloy TNB-V2 between 350–650 °C and 550–850 °C, respectively. A continuous life reduction of Ti6242 was observed with increasing temperature. On contrary, temperature does
