Extract

Titanium aluminide base allays are new materials of interest with exellent potential for high temperature structural applications. Several studies on the fracture toughness of these alloys have been reported and the beneficial effect of lamellar microstructure consisting of Ti3Al(α2) and TiAl(γ) has been detected. While these studies indicate such an enhancement of the fracture toughness is caused by micro-crack toughening, SEM observation alone is insufficient to clarify the fracture mechanism.
