摘要: 等通道彎角擠製為利用模具幾何形狀、材料性質與加工條件來獲得材料的剪力塑性變形。本文使用剛塑性有限元素 DEFORMTM 2D 軟體研究 Ti-6Al-4V 鈦合金於等通道彎角擠製加工的塑性變形行為，在不同擠製條件下，包含模具轉彎之夾角與摩擦因子等，以分析胚料等通道彎角擠製後之破壞因子 (damage) 分佈、有效應力與應變分佈等。最後設計兩組 (φ =90º 和φ =120º) 等通道彎角實驗模具來驗證之。
The shear plastic deformation behavior of a material during equal-channel angular extrusion (ECAE) is governed primarily by the die geometry, the material properties, and the process conditions. This paper employs the rigid-plastic finite element (FE) DEFORM(superscript TM) 2D software to investigate the plastic deformation behavior of Ti-6Al-4V titanium alloy during ECAE processing. Under various ECAE conditions, the FE analysis investigates the damage factor distribution and the effective stress-strain distribution. The relative influences of the internal angle between the two die channels and the friction factors are systematically examined. Finally, two sets of mold and die (including φ=90º and φ=120º) for ECAE are designed to compare the simulated data.
