Study on Constitutive Relationship of Ti-B25High StrengthβTitanium Alloy during High Temperature Deformation AITranslate
Abstract AITranslate
The thermal compression tests of Ti-B25 alloy were conducted on Gleeble 3800 thermal simulator under the conditions of 800~1000℃ temperature,0.01~10s^-1 strain rate and 70% strain.The results show that in the initial deformation stage of Ti-B25 alloy,the flow stress increases rapidly with the increase of strain.However,after reaching the peak value,the flow stress begins to decrease and gradually stabilizes, showing a steady flow characteristic.During high temperature deformation,both steady stress and peak stress decrease significantly with the increase of temperature and the decrease of strain rate.Through regression processing of the data,the functional relationships are fitted between the thermal deformation activation energy Q,the structural factor A,the stress index nor the stress level parameterαand the strainε, and then the constitutive equation of the alloy during high temperature deformation is obtained.
