High temperature low cycle fatigue properties of Ti-48Al-2W-0.5Si gamma titanium aluminide

Low-cycle fatigue and deformation substructures in an engineering TiAl alloy

“…The observed reduction in yield stress and Young's modulus as temperature increases is consistent with the data reported on similar alloys [5,15].…”

Fatigue properties of TiAl alloys

“…Kim [26] had previously reported that duplex microstructures present a higher LCF resistance than fully lamellar microstructures below 850 8C. This is verified in the case of the ABB alloy investigated by Recina et al [22][23][24][25]. Besides, it seems that the behaviour of different duplex alloys is nearly similar, despite of differences in microstructural features and mechanical properties.…”

“…Recina et al [22][23][24][25] have examined the low cycle fatigue (LCF) behaviour of different alloys at 600 8C. Some of their results are presented in Fig.…”

Development of a TiAl Alloy by Spark Plasma Sintering

“…Similar compositions, namely ABB alloys, have already been investigated in the past by using the casting route [34,35], thus resulting in promising creep and fatigue properties. Compared to the casting route, the SPS route provides more homogenous microstructures, which lead to very reproducible properties.…”
