Numerical Simulation of Hot Die Forging Process of Ti-6Al-4V Alloy Blade

Abstract:

Ti-6Al-4V alloy is used extensively in aerospace industries due to its excellent properties. In this paper, the hot die forging process of the Ti-6Al-4V alloy blade was simulated by using 3D finite element method. Based on the model, the effect of process parameters on the deformation was investigated. The results show that the increase of temperature is beneficial to improving the uniformity of stress distribution. The slower the declining velocity of upper die is, the larger the strain gradient of severe deformation area will be. In addition, the stress distribution gets uniform with velocity decreasing. The large friction coefficient can make strain distribution uneven and cause symmetry of stress distribution. The proposed numerical simulation of hot die forging of blade in the present work may yield important information for the development of hot die forging techniques and the manufacture of blade.
