摘要
Microstructure refinement of TiAl alloys is realized by introducing solidification in this paper. The obtained fine-grained cast microstructures can be optimized to be fine-grained fully lamellar structures merely by a one-step heat treatment. The present study may provide an alternative and cost-effective approach for microstructure refinement of TiAl alloys. (C) 2004 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
