摘　　要：The phase composition and microstructure of β'-Sialon/SiC whisker compostie materials were studied by means of XRD ,SEM,EDAX and HREM.Besides β'-Sialon and β-SiC as main crys-talline phases,15R AIN polytypoids presented in the materials,Yttrium,added in Y2O3 as sintering aid,was concetrated mainly in glassy phase,A mosaic structure of SiC whisker in β'-Sialon grains was observed,Two kinds of grain boundaries were also observed:one was a direct-contact grain boundry between β'-Sialon and β-SiC,while the other was a boundary between β'-Sialon grains wqith glassy phases.
