Abstract
A novel type of titanium alloy was investigated in this article. The microstructure and mechanical properties of Ti-3573 and Ti-3873 titanium alloys were observed and measured after 20% hot deformation, respectively. The results shown that both titanium alloys occurred dynamic recrystallization (DR) during hot deformation. The tensile strength of Ti-3873 titanium alloy was better than that of Ti-3573 titanium alloy. Both titanium alloys have fine secondary α-phase which appeared granular or acicular near the β-grain boundaries or within the β-grain after hot deformation. Better tensile strength (847 MPa) of Ti-3873 titanium alloy is contributed to the higher content of β-phase stable element (Mo). The improvement plasticity (12 %) of Ti-3573 titanium alloy is due to the occurrence of dynamic recrystallization during hot deformation.Keywords
