Abstract A novel solid freeform fabrication based on self-propagating high temperature synthesis (SHS) of NiAl intermetallics was examined. SHS produced a superheated NiAl liquid at 2876 K by simply mixing liquid aluminum at 1023 K and liquid nickel at 1773 K in a crucible and casting it into a NiAl bar to study its mechanical and chemical properties. When the two elemental liquids are poured onto a base materials such as steel, the surface of the base material is melted due to the heat generation and that during rapid solidification, the NiAl produced is strongly joined to the base material. Utilizing the exothermic reaction of SHS, high-melting point materials can be produced without the use of external heating. (Edited abstract) 10 Refs. (Auth abstract) XX
