摘要：

To design an alloy with high strength around 1773 K and good ductility at room temperature, the microstructure, the compression strength and the creep properties at 1773 K of the Ir-Al alloys with an fcc and B2 two-phase structure were investigated. High-temperature mechanical properties are discussed in terms of microstructure. (C) 2002 Acta Materialia Inc. Published by Elsevier Science Ltd. All rights reserved.
