Application of Norbury rule to thermal conductivity in intermetallic compounds

Book ·
OSTI ID:78321
Thermal conductivity data at room temperature, which are measured by laser-flash method, are presented in B2 aluminides and titanides, and in nickel based L1{sub 2} compounds. The thermal conductivity {gamma} is changed in the following order of the compounds. {lambda}(NiAl) > {lambda}(CoAl) > {lambda}(FeA), {lambda}(NiTi) < {lambda}(CoTi) < {lambda} (FeTi), {lambda} (Ni{sub 3}Al) > {lambda} (Ni{sub 3}Si) and {gamma}(Ni{sub 3}Ga) > (Ni{sub 3}Ge). According to Norbury rule originally proposed for the concentration dependence of electrical resistivity, the increasing rate is greater in the solid solution, where the position of solute elements is more remote in horizontal distance from a host metal in the periodic table. It is found that this rule holds for the thermal conductivity measured for the intermetallic compounds with the combination of a series of guest constituents and a fixed host constituent both in the B2 and L1{sub 2} intermetallic compounds.
