| Abstract: | When powder mixtures of Fe, Al, Ti and B were heated, sudden and rapid temperature rise was always observed at temperatures near the melting point of Al, and the powder mixtures melted. X-ray diffraction analyses revealed that the reaction products consisted of only FeAl and TiB2. Based on metallographic investigations and electron probe microanalyses, it was found that fine TiB2 particle dispersed FeAl-based composites were synthesized by the above-mentioned exothermic reaction, although the composites included a lot of pores. The use of pseudo-isostatic pressure during the exothermic reaction brought about dramatic reduction in porosity. When the volume fraction of the TiB2 particles increased, their average diameter increased. The increase in the volume fraction of the TiB2 particles also brought about the increase in the Vickers hardness and the volume fraction of pores. The volume fraction of pores was markedly reduced by preheating the powder mixture in vacuum. |
