Irradiation creep tests were conducted on Textron SCS-6 silicon carbid
e (SiC) fibers during irradiation with 14 MeV deuterons at 450 and 600
degrees C. The fibers are produced by a CVD procedure: their microstr
ucture may therefore be representative for the matrix of a SiC composi
te. There is a significant radiation induced increase in creep deforma
tion. Both quantities, irradiation creep strain and creep rate, are hi
gher at 450 degrees C than at 600 degrees C for doses < 0.07 dpa. (C)
