Processing and Testing of RE sub(2)Si sub(2)O sub(7) Fiber-Matrix Interphases for SiC-SiC Composites

Rare-earth disilicates (RE sub(2)Si sub(2)O sub(7)) are investigated for use as oxidation-resistant alternatives to carbon or BN fiber-matrix interphases in ceramic matrix composites (CMC). Dense alpha , beta , gamma -Y sub(2)Si sub(2)O sub(7), and gamma -Ho sub(2)Si sub(2)O sub(7) pellets were form...

description Rare-earth disilicates (RE sub(2)Si sub(2)O sub(7)) are investigated for use as oxidation-resistant alternatives to carbon or BN fiber-matrix interphases in ceramic matrix composites (CMC). Dense alpha , beta , gamma -Y sub(2)Si sub(2)O sub(7), and gamma -Ho sub(2)Si sub(2)O sub(7) pellets were formed at 64 MPa and 1050 degree C-1200 degree C for 1 h using the field-assisted sintering technique (FAST). Pellet modulus was measured using nanoindentation, and Vickers hardness was measured at loads of 100, 500, and 1000 g. The sliding stress of SCS-0 SiC fibers incorporated in alpha -, beta -, and gamma -RE sub(2)Si sub(2)O sub(7) matrices were measured by fiber push-out. Deformation of RE sub(2)Si sub(2)O sub(7) after indentation and after fiber push-out was characterized by TEM. Implications of the results for use of RE sub(2)Si sub(2)O sub(7) as a fiber-matrix interphase in CMCs are discussed.
