| Abstract: | Alloying and solidifying techniques of NiAl intermetallic were presented and reviewed. The effect of alloying on plasticity, ductility and strength of NiAl were described intentionally. And the effect of directional solidification, common casting and single crystal technique on strength and toughness of NiAl were also discussed. The NiAl and refractory metal phase eutectic alloys prepared by directional solidification technique have better strength and better toughness. They have favourable colligate mechanical properties that are favourable in high temperature strength and room temperature ductility. |
