本文研究了Fe3Al金属间化合物的电学性能结果表明，二元Fe3Al有很高的电阻率：二元Fe3Al的电阻率与Al含量有关；合金化可进一步提高Fe3Al的电阻率在20—1100℃范围内．发现Fe3Al的电阻率在某些温度区内存在反常现象，对这一现象本文进行了理论分析.
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.
