The article exhibits non-brittle fracture. 05-21-2015: 20140094355: METHOD FOR PRODUCING SILICON CARBIDE-CARBON COMPOSITE - Provided is a novel method for
Nov 13, 2000· Sintered Silicon Carbide has demonstrated an excellent performance record as ceramic material in composite armor protection systems. The properties of sintered silicon carbide, such as its high hardness, compressive strength and elastic modulus, provide superior ballistic capability when confronted with high-velocity projectiles.
The sintering behavior of silicon carbide using alumina, silica and yttria as additives was investigated. Powders containing 90 vol. % SiC and 10 vol. % additives (keeping 1Y2O3:1Al2O3 molar ratio) were sintered at 1950°C/1h, in a dilatometer or a graphite resistance furnace. Thermal treatments were also done from 1500°C/1h up to 1800°C/1h, in order to evaluate the formation of transient
