Development of Nickel and Nickel-Iron Aluminides for Elevated-Temperature Structural Use


This paper summarizes recent work on alloy design of Ni3Al alloys for structural use at elevated temperatures. Efforts on alloy development have been focused on four areas: (1) improvement of ductility at ambient temperatures, (2) enhancement of high-temperature strength by solid-solution effects, (3) alleviation of dynamic embrittlement in oxidizing environments, and (4) fabrication improvement. Nickel aluminides with promising properties have been developed by microalloying with boron and macroalloying with chromium, zirconium (or hafnium), and iron additions.
