纯镁等通道转角微挤压成型工艺及摩擦效应研究
Study on Forming Process and Friction Effect of Pure Magnesium Equal Channel Angular Pressing
摘要
Abstract
In this paper, high purity magnesium( purity:99.95%) was chosen as research object.The commercial software DE-FORM was utilized to simulate the deformation process of M-ECAP.The flow of material, forming load, equivalent stress and strain and the effect of friction on the M-ECAP deformation process were investigated.The results show that sample tends to be more uni-form and equivalent strain accumulated variables should be increased, grain fine and homogeneous.The plastic is improved effectively. Load increases gradually with the increase of friction factor, while the maximum equivalent strain change is not obvious and the maxi-mum equivalent stress decreases.关键词
