title = "Fabrication of Ti2AlC/TiAl Composites by MA and SPS",
abstract = "In this work, mechanical alloying (MA) of mixed powders of Ti and Al has been used to produce the sintered powders. After milling for 50h, most mixed powders transformed to amorphous phase with small amount of intermetallic phase, and the average powder size reached 5-20 μm. Spark plasma sintering (SPS) technique was used to prepare Ti2AlC/TiAl composites from milled powders with 2 wt\% carbon nanotubes (CNTS) at different sintering temperatures (from 750°C to 1150°C). XRD analysis showed that the sintered bulk materials were composed of γ-TiAl intermetallic compound and Ti2AlC ceramic phase. SEM observations indicated that Ti2 AlC/TiAl composites show a continuous interpenetrating three-dimensional network when sintered above 950°C. Mechanical tests of Ti2AlC/TiAl composites revealed high compression strength and hardness. In addition, a yielding behavior was observed in the Ti2AlC/TiAl composites when sintered above 1050°C, with a yield strength of 1477MPa.",
