Abstract

Ti-5mass%Al, Ti-I0mass%A1, Ti-32mass%Al and Ti-64mass%Al were synthesized by mechanical alloying (MA) of Ti powder and Al powder using a planetary ball milling for 360ks in 66kPa argon gas atmosphere. Ti-64mass%Al powder milled for 360ks was Al solid solution. Non stoichiometric Ti-Al powder milled for 360ks became amorphous state with an increase of Al content in the MA powder.<BR>The mixture of MA powder and Al powder, which contained 64mass%Al, was consolidated by spark plasma sintering(SPS). The starting temperature for shrinkage in SPS process was decreased by the addition of Al powder into MA powder. In the mixture of Ti-5mass%Al MA powder and Al powder, the consolidated TiA1₃ was obtained by SPS at 1073K for 0.3ks. This sintered body had a homogeneous fine microstructure.
