摘要: Abstract Helium-bubble formation behavior in SiC-fiber-reinforced SiC-matrix (SiCf/SiC) composites was studied using helium implantation. Microstructural observation of the He-implanted specimens carried out after post-implantation annealing at 1673 K for 1 h. revealed small cavities SiC matrix only. No were observed fibers or carbon coating layers their interfaces.
