| Popis: | Samples containing equimolar amounts of SiC, AIN and Al2OC were fabricated by hot pressing a mixture of SiC, AIN, Al2O3 and Al4C3. The predominant constituent in the hot pressed material was of 2H crystal type. The samples were subsequently annealed at a temperature up to 2050‡ C for up to 153 h in an atmosphere of nitrogen. Samples made with IbigawaΒ-SiC exhibited formation of needle-type precipitates. Carbon deficient specimens contained substantial amounts of Al3O3N. Principal characterization techniques employed consisted of optical microscopy, electron microscopy, X-ray diffraction and chemical analysis. |
