Abstract

Abstract

A novel two-phase titanium alloy of Ti₈₄Al₁₁FeMo₄ was designed based on d-electron theory and the phase composition as a function of temperature was analyzed. Combined with the thermodynamic calculation results, the evolution relationship between the microstructure and mechanical properties of titanium alloys at different aging temperatures of 700 ℃, 770 ℃ and 850 ℃ was studied, respectively. The results show that the amount of β phase in the microstructure of Ti₈₄Al₁₁FeMo₄ titanium alloy gradually increases with the increase of aging temperature. When the aging temperature is increased to 850 ℃, the amount of β precipitates reaches the maximum, and a large number of small-sized β phases are distributed among the coarse β phases. Ti₈₄Al₁₁FeMo₄ titanium alloy exhibits different mechanical properties after aging treatment at different temperatures. The compressive strength of titanium alloy could be significantly improved after aging at 700 ℃ and 770 ℃, while the high strength and ductility could be simultaneously obtained after aging at 850 ℃.
