Effect of rolling and heat treatment on microstructure and properties of Ti-26 sheet
The effect of heat treatment and rolling process on the properties and microstructures of Ti-26 (Ti-15V-3Al-3Cr-3Sn-Forming) sheet was studied.The results show that the best rolling temperature for Ti-26 alloy is in the temperature range from 900 ℃ to 950℃.Under this condition,the resistance of deformation and yield ratio are low and the alloy has better hot work ability.The alloy will achieve better mechanical properties and completely recrystallized β microstructure when the deformation ratio is not less than 60％ and the solution temperature is 30 ℃ above the phase transformation temperature.The best heat treatment conditions are recommended as: 790℃,30 min,AC or WQ followed by 510 ℃,10 h,AC.Under this heat treatment condition the strength of the Ti-26 alloy is 1 230 MPa and the elongation is 15％.
