ABSTRACT:
Nanoparticles of intermetallic alloys such as FeAl, Fe3Al, NiAl, TiAl and FeCoV exhibit a wide variety of interesting structural, magnetic, catalytic, resistive and electronic, and bar coding applications. The nanosized powders can be used to make structural parts having enhanced mechanical properties, magnetic parts having enhanced magnetic saturation, catalyst materials having enhanced catalytic activity, thick film circuit elements having enhanced resolution, and screen printed images such as magnetic bar codes having enhanced magnetic properties. In contrast to bulk FeAl materials which are nonmagnetic at room temperature, the FeAl nanoparticles exhibit magnetic properties at room temperature.
