Název v původním jazyce

Dependence of electrical resistivity of Fe-Al alloys on composition

Popis výsledku v původním jazyce

A series of binary Fe-Al alloys containing 20 - 40 at.% Al, having ordered D03 (Fe3Al) or B2 (FeAl) structure, was cast from pure elements. For a comparison, specimens were also prepared from corresponding complex Fe-Al alloys with additional alloying elements of C, Cr, Ti, Zr and B. All specimens were investigated in two states, as-prepared and heat treated (723 K/120h). Electrical resistivity was measured at 291 K (RT) and 77 K (liquid N2), respectively, by means of usual potentiometric method. Electrical resistivity data of these series of Fe-Al alloys with and without additional alloying elements are presented and discussed. Differences between resistivity of binary and complex alloys are mainly due to substitution of Fe by Cr in the D03 matrix. The addition of C in alloys with B2 structure lowers the resistivity of the matrix due to kappa-phase Fe3AlCx precipitation.
