Outline of Final Research Achievements

This study aimed to explore substrates, having high-temperature stability and electrical conductivity, for SiC epitaxial growth by developing melt solidification of eutectics comprising SiC and transition metal diborides. We melted and solidified composites of SiC-CrB2 and SiC-VB2 by an arc-melting method and investigated effects of nominal compositions on the resultant microstructure and crystal orientation relationships in the eutectic composites. In SiC-CrB2, the eutectic composition was 22.5 mol% of SiC, in which the minute eutectic structure consisting of fine SiC grains several hundreds of nanometers dispersed in CrB2 matrix formed. The SiC-VB2 eutectic composite at the eutectic composition of 45 mol% SiC exhibited single-crystalline-like unidirectionally solidified microstructure with the crystal orientation relationship of SiC(111)//VB2(1-210) and SiC[0-11]//VB2[0001].
