研究了TiCoSb基半Heusler合金在300~900K温度范围内的晶格导热系数。根据Klemens-Callaway理论[Phys],导出了这些合金高温晶格导热系数的唯象模型计算。修订本119,507(1960);同上。113,1046(1959)]。TiCoSb、TiCo0.5Rh0.5Sb和Ti0.5Zr0.5CoSb的计算值与实验值吻合较好。此外,模型还预测了同时在Ti和Co亚晶格上等电子合金化可以降低晶格热导率,并预测了Ti0.5Zr0.5Co0.5Rh0.5Sb在900K时的κL值为0.3W/mK。
The lattice thermal conductivities of TiCoSb-based half-Heusler alloys are presented in the temperature range between 300 and 900K. A phenomenological model calculation of the high-temperature lattice thermal conductivities of these alloys was derived based on the Klemens–Callaway theory [Phys. Rev. 119, 507 (1960); ibid. 113, 1046 (1959)]. Good agreement was obtained between the calculated and the experimental data for TiCoSb, TiCo0.5Rh0.5Sb, and Ti0.5Zr0.5CoSb. Furthermore, the model predicts that simultaneously isoelectronic alloying on both Ti and Co sublattices could reduce the lattice thermal conductivity, and a κL value of 0.3W∕mK is predicted for Ti0.5Zr0.5Co0.5Rh0.5Sb at 900K.
