中文摘要：

借助DEFORM-3D模拟软件,模拟了二次转角ECAE动态成形Al-Mg-Si合金第1道次应力应变及温度场分布.其最大等效应力为141MPa,应变为31.4,变形温度为415℃,基本与一次转角连续ECAE成形的第2道次相等.效率可达到常规连续ECAE的二倍,因此,本研究对开发Al-Mg-Si合金二次转角连续ECAE成形新工艺具有重要意义.

英文摘要：

The stress-strain and temperature distribution of Al-Mg-Si alloy prepared bydouble turn continuous ECAE forming were simulated by using DEFORM-3 Dsoftware.The maximum equivalent stress is 141 MPa,strain is 31.4 and temperature in the deformation zone is 415℃.The results show that the distribution of equivalent stress-strain and temperature of deformation zone prepared by double turn ECAE forming is almost equal to that prepared by No.2 continuous ECAE forming.The efficiency of double turn continuous ECAE forming is two times higher than that of continuous ECAE.So it is of great significance of this research on developing double turn continuous ECAE forming new technology for Al-Mg-Si aluminum alloy conductors.
