Residual thermal stresses in a filamentary SiC Al …

Residual stresses in a silicon carbide/aluminum ( SiC Al) composite introduced by the cooling process were investigated. The large mismatch of the coefficients of thermal expansion (CTE) between the silicon carbide (SCS-2) fiber and 6061 aluminum matrix tends to produce high residual stresses so that plastic flow of the matrix is inevitable during cool down.

29/2/2012· In 2006, Garcia et al. reported the first PECVD amorphous silicon carbide TFTs. The a-Si 1-x C x :H films were deposited on glass substrates by PECVD at 300ºC using SiH 4 /CH 4 /H 2 gas mixture. Subsequently, n-type a-Si:H layer was deposited using SiH 4 /H 2 /PH 3 gas mixture and a photolithography was performed.

Shock response of polycrystalline silicon carbide …

Longitudinal stress profiles have been measured in polycrystalline silicon carbide (SiC) shocked to peak stresses from 7.3 to 23 GPa. Dispersive wave fronts, consistent with the expected inelastic response, were observed beyond the previously reported Hugoniot elastic limit (HEL) of 11.7 GPa. limit (HEL) of 11.7 GPa.

Layer-Resolved Graphene Transfer via Engineered Strain …

Oriented monolayers of graphene containing some bilayer regions can be formed on silicon carbide crystal surfaces, but, to be cost effective, the graphene needs to be exfoliated and transferred to other substrates so that the silicon carbide crystal can be reused. Kim et al. (p. [833][1], published online 31 October) used a nickel film grown to a thickness designed to impart a particular

Tuning the deformation mechanisms of boron carbide …

Boron carbide suffers from a loss of strength and toughness when subjected to high shear stresses due to amorphization. Here, we report that a small amount of Si doping (~1 atomic %) leads to a substantial decrease in stress-induced amorphization due to a noticeable change of the deformation mechanisms in boron carbide. In the undoped boron carbide, the Berkovich indentation–induced quasi
