of Si and AlN phases during the infiltration process. Key words: AlN; ceramic-matrix composites; thermal properties; liquid metal infiltration 1 Introduction AlN possesses high thermal conductivity (TC... uniform distribution of the ceramic phase and high dimensional stability. AGHAJANIAN et al [13] produced AlN matrix composites by using a pressureless melt infiltration technique. They carried out......

of the composites are shown in Fig.7. Yield phenomenon occurs in the matrix of PE when the strain is 15%, and it does not rupture up to 200% strain of PE. The results clearly show that PE is a typical... and rupture-stresses of the composites becomes very low. Fig.8 shows SEM micrographs of the rupture- surface of the new composites. From Fig.8(a), we can see that PAn and ATTP agglomerate on the matrix of PE......
