Properties and Characteristics of SiC and SiC/SiC Composites

Journal of Nuclear Materials, 2012
The advantageous properties of SiC/SiC composites such as high temperature strength, creep and corrosion resistances, low density, high toughness, resistance to shocks, to fatigue and to damage, and reliability make them ideal candidates for the replacement of metals and ceramics in many engineering applications involving loads, high temperatures and ...

Creep of SiC–SiC microcomposites

Journal of the European Ceramic Society, 1999
Abstract The creep behavior of SiC/C/SiC microcomposites at 1200–1400 °C and 140–450 MPa was investigated in the presence and absence of matrix cracking. The microcomposites consisted of single Hi Nicalon or Carborundum fibers coated with a CVD carbon interlayer and a CVD SiC matrix.

SiC TO SiC WAFER BONDING

MRS Proceedings, 2002
ABSTRACTSiC wafers with an RMS roughness of 1.5 nm were bonded in a dedicated ultrahigh vacuum bonding chamber. Successful fusion of wafers was observed at temperatures as low as 800°C under a uniaxial mechanical stress of 20 MPa. Cross-section transmission electron microscopy (XTEM) of a specimen bonded at 1100°C revealed parts of the interface where ...

Low dose irradiation performance of SiC interphase SiC/SiC composites

Journal of Nuclear Materials, 1998
Abstract Reduced oxygen Hi–Nicalon™ fiber reinforced composite SiC materials were densified with a chemically vapor infiltrated (CVI) silicon carbide (SiC) matrix and interphases of either `porous' SiC or multilayer SiC and irradiated to a neutron fluence of 1.1×1025 n m−2 (E>0.1 MeV) in the temperature range of 260 to 1060°C.

SiC/SiC and SiC/Kovar joining by Ni–Si and Mo interlayers

Journal of Materials Science, 2010
A composite joining technique, using a Ni-56Si filler alloy and Mo as interlayers, was used to join SiC to SiC and to Kovar. The wetting of the Ni-Si alloy on SiC ceramic was studied in a vacuum at 1,350 ?C by the sessile drop technique as a function of time; the nonreactive wetting characteristics in the Ni-Si/SiC system were confirmed, with an ...

Chemical Vapor Infiltrated SiC/SiC Composites (CVI SiC/SiC)

2005
CVI SiC/SiC composites are manufactured via Chemical Vapor Infiltration Process. The SiC-based matrices are deposited from gaseous reactants on to a heated substrate of SiC fiber preforms. An interphase coated on the fibers allows control of damage and mechanical behavior.

Thermal conductivity/diffusivity of SiC-Mullite and SiC-SiC composites

2014
The purposes of this study were to determine as a function of temperature the thermal diffusivity and/or thermal conductivity of SiC-Mullite and SiC-SiC, and to explain the observed behavior in terms of changes in temperature, microstructure, composition, and/or orientation.
