Introduction TiAl-based intermetallics are potential high-temperature structural materials for aerospace, automotive and other applications, due to their high specific strength, excellent oxidation and corrosion resistance, relatively low densities, and adequate creep resistance at high temperatures [1,2].
Experimental Powders of Al (200 mesh, 99.5% purity), Ti (280 mesh, 99.3% purity), TiO2 (0.5 μm, 99% purity), and Fe2O3 (320 mesh, 99% purity) were used as raw materials.
Some of the polished specimens were used for the measurement of the fracture toughness by a single-edge notched beam method with a universal material testing machine (PT-1036PC, Perfect Instrument Co.

Research evidences in damage and fracture mechanics [Lemaitre, 1996; Bridgman, 1964] reveal that steel materials become more brittle with the increasing triaxial tension, measured often by the stress triaxiality ratio, σm/σseq, where σm refers to the mean stress while σseq denotes the effective stress.
