Ion irradiation effects on third generation SiC fibers in elastic and inelastic energy loss regimes
چکیده انگلیسی

Third generation silicon carbide fibers, mainly Hi-Nicalon Type S and Tyranno SA3, have improved the irradiation resistance of silicon carbide composites. In this work the microstructural evolution of these fibers due to ion irradiation is investigated in terms of Raman micro-spectrometry. In comparison with a 6H–SiC single crystal, similar amorphization kinetics have been found for increasing fluences of 4-MeV Au3+ ions. Also, in situ tensile tests have been performed to these micrometric fibers that allow real time tracking of their strain behavior under different in-core-like conditions. Tyranno SA3 fibers have been irradiated with 12-MeV C4+ at 300 MPa at RT and 1000 °C revealing a high influence of the irradiation temperature on the fiber residual strain.
