  Thermal conductivity and thermal expansion of L12 intermetallic compounds based on rhodium

  摘要：

  Thermal conductivity and thermal expansion were measured for the L1(2) intermetallic compounds Rh3X (X=Ti, Zr, Hf, V, Nb, Ta) in the temperature range between 300 and 1100 K to evaluate the feasibility of applying the compounds to high temperature structural materials. The thermal conductivities of Rh3X are widely distributed in the range from 32 to 103 W m(-1) K-1 at 300 K, while the difference of the thermal conductivities becomes less emphasized at higher temperatures. A trend is observed that the thermal conductivity of Rh3X is larger when the constituent X belongs to group 5 rather than 4 in the periodic table. The coefficients of thermal expansion (CTE) of Rh3X slightly increase with increasing temperature, and they are concentrated around 10 X 10(-6) K-1 at 800 K. A trend is that the CTE of Rh3X is reduced as the position of X goes downward in the periodic table. It is demonstrated that Rh3Nb and Rh3Ta are suitable for high temperature structural applications due to the larger thermal conductivities and the smaller CTE. (C) 2003 Elsevier Science B.V.
