日本产业技术综合研究所三上祐史采用机械合金化法制造Fe2VAl合金粉末,用通电烧结法制出烧结体,其热导率降低到18W/mK,约为电弧冶炼法试块的60%,这是本方法制得试样的晶界声子散射使热导率降低之故。若采用重元素W置换V,可使热导率降低50%,对电导率也影响不大。Fe2VAl烧结体通过 Japan Institute of Industrial Technology Mitsuyoshi Uses the mechanical alloying method of manufacturing Fe2VAl alloy powder, sintered by the current sintering method, the thermal conductivity is reduced to 18W / mK, about 60% of the arc smelting test block, which is The grain boundary phonon scattering produced by the method reduces the thermal conductivity. If heavy element W is used to replace V, the thermal conductivity can be reduced by 50%, which has little effect on the electrical conductivity. Fe2VAl sintered body through
