“…Table 1 presents the physical and mechanical characteristics of reaction-sintered silicon carbide, boron carbide, liquid-phase sintered silicon carbide [24] and the composite material "Ideal" [25,26]. According to all mechanical characteristics, the composite material "Ideal" is better than other materials.…”

As an example of the implementation of digital materials science approaches based on statistical processing of electron micrographs with the analysis of fractal parameters, the digital characteristics of microstructure of diamond–silicon carbide ceramic composite material are calculated. The lacunarity parameter characterizing the non-uniform distribution of filler particles in the matrix is found. Based on lacunarity values calculated at different scales, scale invariance parameter characterizing the dependence of lacunarity on the scale is evaluated. Voronoi entropy characterizing the structure based on the quantity of information is also calculated and used to determine the average number of neighboring particles and average distance between them. For the composites with high mechanical properties, the number of nearest neighbors approaches six, indicating an almost closest packing.

“…The effect of diamond grain size (10 µm/50 µm) and temperature of impregnation with liquid silicon (1500 • C/1600 • C) upon the properties of resulting materials was studied and samples with an elasticity modulus of 525 GPa and density of 3.25 g/cm 3 were obtained in [22]. The "ideal" composite in [19] features an elasticity modulus of 720 GPa and sound speed of 15,000 m/s. The best performances (sound speed of 15,500 m/s and elasticity modulus of 800 GPa) were achieved for the composite "Sceleton" ® [20,26] samples containing 70% diamonds.…”

The research aimed at the composition optimization for diamond-SiC-Si composites. The effect of a porous diamond workpiece was studied on the properties (porosity, density, modulus of elasticity, phase composition) of the product of its siliconization with molten silicon. The lowest porosity and highest modulus of elasticity were observed in the case of using mixed matrices with the maximum size of diamond grains of 250/200 μm for siliconization. The best results in terms of the sound speed (16,600 m/s) and elasticity modulus (860 GPa) were achieved by microwave processing of a composite containing detonation nanodiamonds.
