Summary:Two-phase titanium alloy sample which initial microstructure is equiaxed have been tested by the Gleeble-3500 thermo-analogue machine with the isothermal and constant strain rate, the constitutive relationship of the titanium alloy was constructed by analyzing true stress-strain curve under different hot deformation conditions and considering the effect of the strain rate, deformation temperature and strain on flow stress synthetically. Error analysis shows that the constructed constitutive relationship has good accuracy, in the range of 900 ~ 1150 °C the error is less than 10% of the data points are accounted for 97.4% of all data points, can conform the requirements of plastic processing.
