Development of AlN and TiB(2) Composites with Nb(2)O(5), Y(2)O(3) and ZrO(2) as Sintering Aids

The synthesis of AlN and TiB(2) by spark plasma sintering (SPS) and the effect of Nb(2)O(5), Y(2)O(3) and ZrO(2) additions on the mechanical properties and densification of the produced composites is reported and discussed. After the SPS process, dense AlN and TiB(2) composites with Nb(2)O(5), Y(2)O...

description The synthesis of AlN and TiB(2) by spark plasma sintering (SPS) and the effect of Nb(2)O(5), Y(2)O(3) and ZrO(2) additions on the mechanical properties and densification of the produced composites is reported and discussed. After the SPS process, dense AlN and TiB(2) composites with Nb(2)O(5), Y(2)O(3) and ZrO(2) were successfully prepared. X-ray diffraction analysis showed that in the AlN composites, the addition of Nb(2)O(5) gives rise to Nb(4)N(3) during sintering. The compound Y(3)Al(5)O(12) (YAG) was observed as precipitate in the sample with Y(2)O(3). X-ray diffraction analysis of the TiB(2) composites showed TiB(2) as a single phase in these materials. The maximum Vickers and toughness values were 14.19 ± 1.43 GPa and 27.52 ± 1.75 GPa for the AlN and TiB(2) composites, respectively.
