The isothermal constant strain rate compression experiment of Ti60 alloy samples was carried out by Thermecmaster-Zthermal processing simulation machine.The flow stress behavior of the alloy in at 600～950℃and 0.001～10 s

-1

was investigated

and the artificial neural network（ANN）constitutive model was constructed.The results reveal that the flow stress of Ti60 alloy is decreased with the increase of deformation temperature and the decrease of strain rate.The flow stress-strain curves of Ti60 alloy is characterized by steady flow type and soft flow type under different deformation conditions.The constitutive model established based on ANN has the satisfied prediction accuracy.The relative error between the experimental value of flow stress and the predicted value is basically ranged within ±5%

and the average relative error is 1.82%

meanwhile

the correlation coefficient tends to 1

which can accurately describe and predict the flow stress behavior of Ti60 alloy.
