Abstract：
|
|
In order to study the influence of grain dimension on microforming process at room temperature,micro forward extrusion process with micro copper rods with different grain sizes were proceeded,and the characteristics of material flow in micro dimension as well as relevant processing parameters were obtained.The results indicate that,with the increase of grain size,the extruded rod length becomes gradually irregular and the unit pressure of upper die decreases,while the change of grain dimension has less influence on the tendency of forming load at different forming stages.
