TiB whiskers reinforced pure Ti (TiBw/Ti) composites with a novel network microstructure were successfully fabricated by reaction hot pressing (RHP).TiBw are in situ synthesized around the large pure Ti matrix particles, and subsequently formed into TiBw network structure.The novel TiBw/Ti composites with a network microstructure exhibit a superior combination of mechanical properties.In order to further improve the mechanical properties and guide the subsequent plastic forming, the rolling deformation behavior of the novel composites was investigated.The results show that the strength of the novel TiBw/Ti composites can be effectively enhanced by rolling deformation due to the matrix deformation strengthening effect, and increase with increasing the rolling reduction.The strength of 8.5vol.%TiBw/Ti composite is increased from 845MPa to 1030MPa by rolling deformation.It is certain that the TiB whiskers are gradually broken with increasing the rolling reduction, which is harmful to the mechanical properties of the composites.
