Three stage yielding phenomenon in a NiAl-Fe alloy
- Shanghai Jiao Tong Univ. (China). Dept. of Materials Science
The binary NiAl alloy is extremely brittle at ambient temperatures, so it is withdrawn from practical applications as structural materials or shape memory alloys. It has been found that iron is one of the effective elements in improving the ductility of the NiAl alloy. The NiAl-Fe alloys with ([gamma]+[beta]) dual-phase microstructures have good ductility and also good hot-working properties. These results provide the possibility for using the NiAl-Fe alloys for commercial use. However, there are still many experiments to be performed before these alloys can be practically used. The present paper reports a part of the authors work on the deformation behavior of a NiAl-Fe alloy with a ([gamma]+[beta]) microstructure.
