SiC fiber was used to strengthen tungsten due to its coefficient of thermal expansion close to W, high high-temperature strength and stability to neutron irradiation. Composites were prepared by hot press using W powders and W foils at different temperature (1500 °C, 1700 °C and 1900 °C). The results showed that composites sintered at 1500 °C and 1700 °C had obvious pseudo-ductile behavior.
