摘要: High-density SiC-AIN compositions were fabricated from powder mixtures by hot-pressing in the 1700° to 2300°C temperature range. At 2100°C, a 2H solid solution was found =35 100 wt% AlN. The single-phase samples had steep composition gradients of >10%/μm within grains. Lattice parameters closely followed Vegard's law. For with <35% AIN, multiphase assemblages found. Increasing grain size observed for increasing firing SiC and AIN. Grain solutions significantly smaller than or AIN fired same temperature. Microhardness values decreased linearly region content. Flexural strengths size. SiC, low materials hot-pressed at 2100°C.
