composites were synthesized by one step resistive sintering method. Process
time had been completed in 90 second using 1.5-1.7 Volt and 2000 Amper direct current.
Ti and Al elemental powders were mixed by the stoichiometric ratio
corresponding to the TiAl <sub>3 </sub> intermetallic phases’ with molar
proportion of 1:3. We aimed to obtain some residual ductile Ti phase as well as
the TiAl <sub>3 </sub> major phase in structure. XRD analyses detected the only
phases in the composite were Ti and TiAl <sub>3 </sub>. TiAl <sub>2 </sub> phase
also detected as trace peak in the XRD Chart. SEM examinations showed a dense
microstructure with low amount of porosity. The relative density of the sample
measured according to Archimedes’ principle was 98,7%, and the microhardness of
the sample was about 455±20 HV. </span>}, number={2}, publisher={İskender AKKURT}
