A review of recent developments on Fe sub 3 Al-based alloys
- Metals and Ceramics Division, Oak Ridge National Laboratory, Oak Ridge, Tennessee (USA)
Fe{sub 3}Al-based iron aluminides have been of interest for many years because of their excellent oxidation and sulfidation resistance. However limited room temperature ductility ({lt}5%) and a sharp drop in strength above 600 {degree}C have limited their consideration for use as structural materials. Recent improvements in tensile properties, especially improvements in ductility produced through control of composition and microstructure, and advances in the understanding of environmental embrittlement in intermetallics, including iron aluminides, have resulted in renewed interest in this system for structural applications. The purpose of this paper is to summarize recent developments concerning Fe{sub 3}Al-based aluminides, including alloy development efforts and environmental embrittlement studies. This report will concentrate on literature published since about 1980, and will review studies of fabrication, mechanical properties, and corrosion resistance that have been conducted since that time.
