英文摘要HfC dispersion strengthened tungsten alloys were prepared by the spark plasma sintering (SPS) and an ordinary sintering followed by swaging, respectively. The HfC content is optimized as 0.5 we6 through spark plasma sintering (SPS) processing. The thermal stability, thermal conductivity and mechanical properties of swaged W-0.5 wt%HfC (WHC05) alloys were systematically investigated. Grain of swaged WHCO5 has an obvious round bar shaped morphology with an average diameter of 24.5 gm and an average length of 187 mu m, respectively, which keeps stability with increasing annealing temperature up to 1400 degrees C. The ductile-brittle transition temperature of swaged WHCO5 is about 250 degrees C, much lower than that of SPSed WHCO5 samples (similar to 500 degrees C). The ultimate tensile strength of swaged WHCO5 alloys annealed at 1200 degrees C has no significant drops in a wide tested temperature range from 300 degrees C to 800 degrees C. The thermal conductivity of swaged WHCO5 annealed at 1200 degrees C is up to 174 W/m.K at room temperature and always larger than 137 W/m.K from RT to 500 degrees C, which is much higher than that of the unannealed one and just the same with ITER grade W.
