N2 - Thermal conductivity of A3B intermetallic compounds, where A denotes iron or nickel and B denotes group IIIb or IVb elements, is investigated by a laser-flash method. Among six kinds of L12, compounds, the largest thermal conductivity observed is 32.8 W m-1 K-1 of Ni3Ga. In Fe3Ga and Fe3Ge, three polymorphs, i.e. L12, D019 and D03, can be achieved by performing a suitable heat treatment. Thermal conductivity of the D019 phase is quite close to that of the L12 phase, while the D03 phase shows smaller values. In most A3B compounds, the measured thermal conductivities tend to decrease as the position of constituent B becomes horizontally more distant from that of constituent A in the periodic table.
