Abstract
A harmonic-structured composite with a fine grain Ti-48 mol%Al alloy network and dispersed coarse grain pure titanium is produced by extrusion sintering using the spark plasma sintering (SPS) process. The conditions of extrusion sintering by the SPS process are a sintering temperature of 1073 K, a holding time of 1.8 ks and an extrusion pressure of 100 MPa with a pressurization rate of approximately 0.1 MPa/s. The extrusion compact has a rod shape with φ5×48 mm. The extrusion compact is composed of an elongated harmonic structure with the Ti-48 mol%Al alloy network and the dispersed pure titanium. The Vickers hardness of the extrusion compact is about 220 Hv, which is almost the same as that of a conventional compact.
