摘要：

Multiphase Mo-Si-B alloys are potential candidates for ultra-high temperature application. The T-2/Mo-ss and (Mo,Nb)(ss)/T-1/T-2 eutectic alloys have been grown using an optical floating zone method. In this paper, their microstructure, fracture toughness at room temperature and strength at high temperatures are investigated. (C) 2003 Acta Materialia Inc. Published by Elsevier Science Ltd.
