摘要：
A high performance beta titanium metal matrix composite (TMC) reinforced with in situ TiB particles has been developed via a low-cost blended elemental (BE) powder metallurgy process. The TMC shows anomalous mechanical properties as a titanium based material in tensile and fatigue strength, Young's modulus and wear resistance. Besides the high performance, the TMC has the potential to be fabricated at a lower cost far below that of the practical titanium alloys made by the conventional ingot metallurgy process. The as-sintered density of the TMC reached to 99% of theoretical with a unique activation sintering mechanism and has an excellent hot-workability superior to that of the conventional unreinforced Ti-6Al-4V alloy.
