dc.description.abstractDue to their density and mechanical properties TiAl-based alloys are very interesting materials for aerospace applications. Spark plasma sintering (SPS) is found to compact powders satisfactorily through the simultaneous application of direct current pulses of high intensity and pressure. Some works have studied the sintering of TiAl by means of SPS and it is believed that it is possible to obtain very fine microstructures and very interesting mechanical properties. As raw materials, normally pre-alloyed powders have been used, obtained by atomization or mechanical alloying. However, few works have studied the consolidation of elemental powders. This work presents the synthesis and densification of TiAl-based alloys by means of Spark Plasma Sintering (SPS) using elemental powders as raw materials. The selected composition was Ti-48Al-2Cr-2Nb. The evolution of the microstructure with the temperature is presented and in addition the diffusion of the elements (including heavy metals Cr and Nb) is studied.en
