Thermal deposition of reactive metal oxide/aluminum layers and dispersion strengthened aluminides made therefrom

Metal aluminides are formed by an initial thermal deposition process which forms an intermediary material comprising elemental aluminum and another elemental metal, as well as an oxide of the other metal. The thermally formed intermediary material is subsequently heated to initiate an exothermic rea...

More Information
Summary:Metal aluminides are formed by an initial thermal deposition process which forms an intermediary material comprising elemental aluminum and another elemental metal, as well as an oxide of the other metal. The thermally formed intermediary material is subsequently heated to initiate an exothermic reaction which forms the metal aluminide material. The reaction may be initiated by localized or bulk heating of the intermediary material, and may involve reaction between the aluminum and elemental metal as well as a thermite reaction between the aluminum and the metal oxide. The resultant metal aluminide material may be substantially fully dense and may contain oxide strengthening precipitates such as aluminum oxide.
