Abstract
Titanium-based metal-matrix composites (MMCs), reinforced with 20vol.% TiB particle is produced by mechanical alloying-spark plasma sintering. The compacting of the sinteredshows 98.8% in relative density and about 630Hv. In order to improve the density, hot rolling (reduction ratio of 2.5:1) is conducted. The results show that the vickers hardness increases by about 5%. and 99.9% becomes in relative density. The tensile test is conducted under the quasi-static loading, the ultimate tensile strength of 1173MPa exhibiting. However, it breaks during the elastic deformation. Also, as loading rate increases from 10^1 to 10^3s^<-1>. the dimple becomes large, and deep.
