摘要：
TiB/Ti-6Al-4V composites with controllable orientation were synthesized by powder consolidation and hot extrusion. The in situ reaction of TiB2 and Ti-6Al-4V occurs during hot extrusion. The produced composites show an excellent tensile strength of 1350 +/- 20 MPa and an elongation 4.5 +/- 0.5% due to distribution of the TiB whiskers along extrusion direction.
