Abstract:

Sintered compacts fabricated by spark plasma sintering (SPS) at 1050 ^оС were investigated. Titanium and aluminum powders in a ratio of 25 % (at.) and 75 % (at.) respectively were chosen as starting materials. Powder mixture heating up to elevated temperatures led to a partial loss of an aluminum component and to the formation of a multiphase structure consisting of Al₃Ti, Al₂Ti, AlTi and AlTi₃. The density of sintered powder mixtures was 3.7 g/cm³; an average microhardness value was about 470 HV.
