The effect of ultrasonic vibration on aluminum 1070 alloy in the ECAE process is analyzed using DEFORM-3D software by finite element methods (FEMs). Firstly the result of experiment is applied to improve the accuracy of DEFORM-3D software in ECAE process. The effect of different ultrasonic amplitudes and outer corner angles (Ψ) on the punch load and strain inhomogeneity is discussed . The result reveals that ultrasonic vibration can decrease the punch load and improve the strain inhomogeneity by increasing the ultrasonic amplitude Wei-ching Yeh 葉維磬 2013 學位論文 ; thesis 96 zh-TW
