1D SiC_f-YMAS glass-ceramic composites: microstructure, interfaces and creep behaviour

摘要

This paper presents some results on a glass-ceramic matrix composite (CMC): SiC_f-YMAS. The matrix is made of yttrium disilicate and cordierite. The fiber/matrix interface is always composed of a minimum of two interphases: a carbon interphase and a transition layer. These composites present a good creep resistance at 1223K, with a threshold stress of about 150 Mpa.
