Thermal conductivity of B2-type aluminides and titanides

摘要: Thermal conductivity measurement by the laser-flash method adopted here is very suitable for intermetallic compounds, some of which are too brittle preparing samples with good geometry. data at room temperature presented in series aluminides, FeAl, CoAl and NiAl, titanides, FeTi, CoTi NiTi, gallides CoGa NiGa, order to reveal role 8A group elements first transition metal series. reaches a maximum stoichiometry decreases deviations from on either side most these compounds. The largest thermal conductivities observed 92 W m−1 K−1 NiAl among 23 NiGa 73 FeTi titanides. It discussed that further reduced as position partner components becomes distant host component.
