The electrical properties of alloys of the ruthenium-aluminum system have not previously been the subject of a published work, although the mechanical properties and electronic structure have been investigated. The intermetallic compound ruthenium aluminide (RuAl) is reported to exhibit toughness and good ductility under compression at ambient temperatures, relative to other intermetallic materials, as well as strength and oxidation resistance at elevated temperatures. In the work described in the present paper, a series of alloys in the vicinity of the equiatomic composition, together with alloys close to the eutectic composition, have been investigated in order to determine the influence of composition and temperature on electrical resistivity and thermo-emf.
