Thermecmast-Z thermal processing simulation machine was used to conduct thermal compression experiments on Ti60 alloy samples under the conditions of deformation temperature of 850～950 ℃

strain rate of 0.001～10 s

-1

and true strain of 0.51

to obtain the measured flow curves of the alloy.The traditional friction correction model and the modified friction correction model were adopted to correct the measured flow curve

respectively.The results show that the friction effect has a significant influence on the flow stress of Ti60 alloy.Through un-even deformation of materials

the measured value of flow stress is higher than the true value.Compared with traditional friction correction

the flow curve corrected by modified-corrected friction can better reflect the dynamic response of the flow stress of Ti60 alloy to the true strain.With the increase of strain

the influence of friction effect on the flow stress becomes more significant.
