This paper describes the segregation behaviour of two TiAl alloys containing refractory metal additions. This includes the coring of the refractory metal additions in the beta dendrites and the formation of large peritectic alpha(p) in the interdendritic liquids. The origin, nature, distribution and processing influence of such inhomogeneity are discussed. (c) 2005 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
