Titanium Composite Material and Method for Making It

Abstract

A titanium composite material includes a titanium matrix material and a powder reinforced composite material with a volume ratio of 10%-70%. The titanium matrix material is disposed at an α phase, a β phase, an α+β phase, an omega phase, or an intermetallic α-1, α-2, α-3 phase. The powder reinforced composite material is selected from a ceramic powder material, a powder material with electric features or a magnetic powder material. Thus, the powder reinforced composite material is added into and combined with the titanium matrix material to form the titanium composite material by casting, agglomerating or pressing, so that the titanium matrix material contains the physical, chemical or electric features of the titanium matrix material and the powder reinforced composite material.
