In situ TiC particle, Ti 3 SiC 2 bar and ultrafine Ti 5 Si 3 needle reinforced Ti6Al4V (TiCþTi 3 SiC 2 þTi 5 Si 3 )/Ti6Al4V) composites with a tailored distribution were sucessfully designed and fabricated. The first-scale tailored architecture of reinforcement is the in situ synthesized Ti 3 SiC 2 bars and nearequiaxed TiC particles on the network boundary around Ti6Al4V particles. The secondary-scale architecture is the ultrafine Ti 5 Si 3 needles precipitated in intergranular b phase of center Ti6Al4V matrix particle. The results showed that the two-scale tailored architecture of different reinforcements can significantly improve strength remained with moderate ductility of the composites.
