摘要	In the current study, alloys of Ir-11Al, Ir-23Al, Ir-30Al, Ir-41Al and Ir-45Al (at.%) were prepared to investigate the microstructure and oxidation behaviour of Ir-rich Ir-Al alloys. Ir(Al)(ss) and/or beta-IrAl intermetallic phases were found to exist in the prepared alloys. During isothermal oxidation at 1100 degrees C, the Ir(Al)(ss) and beta-IrAl individually changed to porous and dense Al2O3. The microstructure of the oxide scale formed on Ir-23Al was similar to that of its former alloy which possessed a dendrite-like configuration. It was found that the mass change of Ir-45Al followed a parabolic law, showing the best oxidation resistance among the Ir-Al alloys. (C) 2014 Elsevier Ltd. All rights reserved.
