Silicon Carbide | Tech Ceramic

Hot isostatically pressed silicon carbide (HIPSiC) has even higher mechanical properties compared to the non-pressure sintered SSiC as the components become almost non-porous due to the additional pressures up to approx. 2000 bar during the sintering process.

Tensile Strengths of Silicon Carbide (SIC) Under Shock Loading

Abstract The present work was initiated to measure and compare tensile strengths (i.e., spa11 thresholds) of five different types/varieties of silicon carbide materials. Two of these materials were sintered, and the remaining three were hot-pressed. Three

Texture in hot-pressed silicon carbide -Journal of the …

Abstract A Abstract Systematic studies of the effects of crystalline forms of starting powders and p processing variables on the texture of hot - pressed silicon carbide are described. The results I indie that hot - pressing of $\beta$ - SiC can produce strong textures and composite type duplex microstructure due to the ${\beta} {\rightarrow} {\alpha}$ phase transformation of SiC.

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
