Abstract

TiB whiskers reinforced high temperature titanium Ti60 alloy (TiBw/Ti60) composites with a novel network microstructure have been successfully fabricated by the system of large spherical Ti60 powders and fine TiB₂ powders. The results show that TiB whiskers are in situ synthesized around large Ti60 matrix particles and then formed a novel three-dimensional (3D) network microstructure. The high temperature tensile strength can be improved by fabricating network structured composites. Moreover, the strength of the composites is increased with increasing the reinforcement volume fraction. The tensile strength of 8vol.%TiBw/Ti60 composites with a network microstructure is increased by 61.1%, 57.4% and 45.5% compared with that of the monolithic Ti60 alloy at 600°C, 700°C and 800°C, respectively. The superior improvement can be mainly attributed to the network microstructure, grain refinement and usage of large spherical Ti60 powders.
