Abstract
The ductility of TiAl intermetallics can be improved through stabilizing the ductile β phase. New β-stabilized Ti-45Al-xFe-yMo (x, y=1, 2, 3, 4) alloys were designed through adding the β stabilizing elements Fe and Mo. The microstructural evolution and deformation behavior of the Ti-45Al-xFe-yMo alloys were investigated. The results show that the amount of β(B2) phase is increased with the increase of alloying elements. Mo shows a higher capability for stabilizing the β phase than Fe. In the optimized Ti-45Al-3Fe-2Mo alloy, the grains are significantly refined to about 12 μm, and this alloy shows a very good hot ductility at the elevated temperature.
