| Abstract: | Nanocrystalline NiAl was synthesized by mechanical alloying elemental powders and hot pressing. During milling the reaction mechanism of NiAl was attributed to explosive reaction induced by mechanical collision. The nanocrystalline NiAl material was much stronger and ductiler then conventional coarse grained NiAl at room temperature. |
