The results show that particularly fine and homogeneous microstructures without strong segregation can be obtained for certain alloy compositions solidifying through the β phase. This behavior can be attributed to the avoidance of peritectic solidification and to the alloying influence on the kinetics of the β implies α transformation following solidification. The experimental findings were used to propose a design concept for γ-TiAl + α2-Ti3Al alloys. This concept aims at the production of high-quality castings as well as at ingot material for wrought processing routes because the chemically homogeneous and fine-grained microstructures would be a good precondition for improved workability.}, note = {Online available at: \url{http://dx.doi.org/10.1016/j.intermet.2006.05.003} (DOI).
