Outline of Final Research Achievements

It has been shown that AlTi-TiB2 composites in which sub-micron sized TiB2 particles are dispersed in AlTi matrix can be formed by the reaction sintering of AlTi2 intermetallic compound and boron powders at 1300C using spark plasma sintering method. It is important that AlTi2 intermetallic compound is formed before the addition of boron to suppress the grain growth of TiB2. It has also been shown that, by the sintering of TiB2 with the addition of (AlTi2+2B) mixed powder as sintering aid, AlTi-TiB2 composite with hardness as high as 2500Hv can be obtained.
