Microstructural investigation of interfaces in CMCs
Autor: Jean Vicens, S. Darzens, G. Boitier, J. L. Chermant
Publikováno v: Composites Part A: Applied Science and Manufacturing. 33:1467-1470
This paper is focused on the importance of pyrocarbon interfaces in two types of ceramic matrix composites (Cf–SiC and SiCf–SiBC), during creep tests under argon. The development of micromechanisms which consume energy and then allow a damage tol

Understanding the creep behavior of a 2.5D Cf–SiC composite. III. From mesoscale to nanoscale microstructural and morphological investigation towards creep mechanism
Autor: Jean Vicens, G. Boitier, J. L. Chermant
Publikováno v: Materials Science and Engineering: A. 313:53-63
A multiscale microstructural and morphological investigation of the creep tested 2.5 D C f –SiC specimens has been conducted via scanning, transmission and high resolution electron microscopies (SEM, TEM and HREM) and automatic image analysis. Five

Understanding the creep behavior of a 2.5D Cf–SiC composite
Autor: G. Boitier, J. L. Chermant, Jean Vicens
Publikováno v: Materials Science and Engineering: A. 289:265-275
Macroscopic results for a 2.5D C f –SiC composite creep tested in tension are presented. After the development and the optimization of a new accurate high temperature tensile device, tests were conducted in argon, under a reduced pressure, for stre

The importance of damage and slow crack growth in the creep behavior of ceramic matrix composites
Autor: Jean-Louis Chermant, G. Boitier
Publikováno v: Advanced Composite Materials. 8:77-85
Three ceramic matrix composites (CMCs) were investigated after creep tests: a 2D SiCf-MLAS, a 2D SiCf-SiC and a 2.5D Cf-SiC. The damage features of each one are identified, using optical and scanning electron microscopies (SEM), and the complete dama

Microstructure and creep of 2·5D Cf–SiC Composites
Autor: G. Boitier, Jean Vicens, Jean-Louis Chermant
Publikováno v: Journal of the European Ceramic Society. 18:1835-1843
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 mba
