摘要：
A new TiAl alloy has been developed, with a composition of Ti-42Al-5Mn (at.%). The manufacturing process employs a conventional hot working, in which the cast ingot is heated to the beta + alpha region, subsequently forged or rolled during cooling. Manufacturing of TiAl blades and structural components by this process is demonstrated. (C) 2002 Acta Materialia Inc. Published by Elsevier Science Ltd. All rights reserved.
