A Ti–44.1 at%Al–1.6 at%Mn alloy with unidirectionally oriented lamellar structure was made by using heavy extrusion of a mixture of titanium and Al–Mn alloy powder followed by reactive sintering under HIP. Compression tests were performed for 5 × 5 × 6 mm samples prepared in such a way that angle between the extrusion direction and compression one becomes 0°, 30°, 45°, 60° or 90°. The yield strength at 293 K is found to strongly depend on the above angle, i.e., the 0° sample shows the highest strength, the 90° sample the second while the other samples show much lower strengths. A similar anisotropic yield strength is observed for the results obtained at 1073 K although the strength of the 0° sample is much higher than that of the 90° one. Anisotropic deformation behavior observed in the present investigation is discussed in comparison with that for TiAl PST crystals reported by Fujiwara et al..
