Confirmation of conformity between transition temperature and forging heating temperature of TA15 titanium alloy
Aiming at the conformity problem between the transition temperature and the forging heating temperature of two-phase zone(α+β)of TA15 titanium alloy,several batches of compara-tive process verification were carried out on TA15 titanium alloy bar and forgings.The results showed that the effective range of phase transition point determination of TA15 titanium alloy bar was between 992～996℃,according to the selection principle of phase transition point,the forging heating temperature of two-phase zone(α+β)was cured(955±5)℃and tested,the parameters such as shape,size,mechanical properties,high and low size structure,ultrasonic testing of the forgings all met the specified technical requirements.
