Based on the structure feature of high-rubbed and thin-walled titanium alloy blade,the effects of the initial forging temperature,velocity and friction factor were studied with the method of FEM simulation,Selecting the optimized process parameters for physical experiment,the results show that under the conditions of initial forging temperature of 920℃,press speed of 0.5mm/s,friction coefficient of 0.1,the isothermal forging products can meet the quality requirements.
