Microwave (MW)-assisted combustion synthesis of micrometric metallic powders for the preparation of intermetallic-based materials

Rosa, Roberto; Veronesi, Paolo; Leonelli, Cristina; Corradi, A. B.

Due to the interesting combination of lightweight and high refractoriness, Al-based intermetallic compounds are candidate materials for high temperature applications like turbochargers and exhaust valves. Microwaves (MW) at the frequency of 2.45 GHz were used to ignite the combustion synthesis of elemental micrometric powder mixtures belonging to Fe-Al, Co-Al and Ni-Al systems. The use of a single mode MW applicator allowed undertaking for the first time a comparative investigation concerning the effects of positioning the samples in predominant electric or magnetic field during synthesis. Moreover the effect of microwave irradiation exposure time, after ignition of the highly exothermic reactions, has been investigated as well.
