Abstract

The electrical properties of Fe3Al intermetallics have been studied. The results indicate that the binary Fe3Al alloys have high electrical resistivity which relates to Al content. Additions of alloying elements further increase the electrical resistivity. An anomalous relationship between resistivity and temperature has been found in the temperature range of 20-1100℃,and the mechanism of the phomenon has also been discussed.

Key words: Fe_3Al electrical properties electrical resistivity Fe_3Al electrical properties electrical resistivity
