Silicon Carbide SiC Material Properties - …

Silicon carbide is composed of tetrahedra of carbon and silicon atoms with strong bonds in the crystal lattice. This produces a very hard and strong material. Silicon carbide is not attacked by any acids or alkalis or molten salts up to 800°C. In air, SiC forms a protective silicon oxide coating at 1200°C and is able to be used up to 1600°C.

Carbon corrosion of alloys at high temperature

Minority components silicon and aluminium lead to development of a continuous oxide layer beneath the chromia scale in one case (Figure. 1(a)). This slows the chromia scale growth rate and simultaneously improves its ability to block carbon entry. The alloy shown in Figure 1(b) has a low silicon content (0.6 wt%), insufficient to form a continuous

Newtonian flow process in polycrystalline …

12.09.2004· Some previous studies on hot-pressed and sintered SiC polycrystalline materials have been reexamined. Mechanical data and microstructures strongly suggest that the Newtonian creep behaviour observed in these SiC materials was induced by a disloion process operating in Harper-Dorn creep, rather than by diffusional creep as concluded before.

Flexural fatigue behavior was investigated on titanium (Ti-15V-3Cr) metal matrix composites reinforced with cross-ply, continuous silicon carbide (SiC) fibers. The titanium composites had an eightply (0, 90, +45, -45 deg) symmetric layup. Fatigue life was found to be sensitive to fiber layup sequence. Increasing the test temperature from 24 °C to 427 °C decreased fatigue life.
