The SP700 titanium alloy was subjected to an isothermal constant strain rate compression experiment on the Gleeble-3800 thermal simulation testing machine. Perform friction correction and temperature correction on the flow stress curve were conducted under the process parameters of the deformation temperature of 700～950 ℃ and the strain rate of 0.001～1 s

-1

and the influence of friction effect and temperature effect on the flow stress of the material during the thermal compression experiment was analyzed. The results indicate that the friction correction coefficient is significantly affected by the deformation temperature and strain rate

of which the change law is not obvious yet. In addition

friction effect and temperature effect have significant effects on the thermal compression flow stress of SP700 titanium alloy with obvious rules

and the effect of friction is greater than that of temperature under the conditions of thermal deformation parameters.
