| 英文摘要 | Continuous SiC fiber reinforced titanium matrix composites (SiCf/Ti) have been identified as promising materials for aerospace structures. In this study, SiCf/Ti55531 composites were prepared by hot isostatic pressing(HIP), the effects of longtime aging heat treatment (HT) at low temperatures on the interface morphology and microstructure of SiCf/Ti55531 composites were analyzed by XRD, SEM, EBSD, and TEM. The tensile properties and the fracture mechanism of the composites in both states were evaluated. The tensile strength of SiCf/Ti55531 composites increases after heat treatment, and the fracture mechanism does not change, showing sequential fracture of interface, fiber, and matrix. The matrix plays an important load-bearing role in the tensile process. The enhanced mechanical properties can be primarily attributed to the matrix strengthening. The strengthening mechanisms are that the precipitation of alpha s and lattice distortion hinder the dislocation movement and the texture level parallel to the fiber axis is improved. |
