Abstract
In view of the development of improved TiAl cast alloys the potential of the transformation and its dependence on the addition of several alloying elements has been investigated. It was found that microstructural refinement in solidifying alloys can be attributed to the alloying effect on the kinetics of the transformation. This also holds for grain refinement through Borides which apparently serve as nucleation sites for the phase in the solid-state transformation.
