摘要：

Tensile creep tests have been performed on 2.5D C-f-SiC composites in parallel to a microstructural characterisation down to the nanometric scale. These ceramic matrix composites (CMCs) appear to be creep resistant when tested under argon (50 mbar), between 1273 and 1673 K, at 110 and 220 MPa. The nanostructure of the different phases involved in the as-received material has been determined via HREM. Microstructural changes and search for creep mechanism have been achieved by SEM. Different types of cracks have been evidenced, and the major role of the fibre/matrix interphase was demonstrated by HREM on tested samples. (C) 1998 Elsevier Science Limited All rights reserved.
