摘要：
A silicon carbide, with a preferred orientation of platelet grains, was obtained by hot-forging the hot-pressed SiC with equiaxed microstructures. Increased strength (810-1150MPa), fracture toughness (4.4-5.9MPam(1/2)), and hardness (24.4-26.8GPa) were achieved in the hot-forged specimens compared to the hot-pressed specimens with random orientation.
