Abstract Hastelloy C-276 fiber made by bundle-drawing was employed as raw material， and then the fiber felt blank was prepared through shearing fiber， preparing mesh by wet method and superposing mesh. According to orthogonal experiments， the hastelloy C-276 fiber felt samples were prepared by vacuum pressure sintering. The effect of sintering temperature， holding time and pressure on the loss rate of bubble point pressure was studied. The results show that sintering temperature is the most significant factor influencing the loss rate of bubble point pressure. The optimum sintering process for hastelloy C-276 fiber felt is sintering temperature of 1 150 ℃， holding time of 4.5 hours and pressure of 0.8 kPa.
