Experimental Investigation on Local and Global Texture Evolution in Drawing Seamless Copper Tubes

Mass flow inequality in the initial stage of tube processing can lead to eccentricity and micro- nano-structural changes that affect residual stress texture development. In this study, macro- micro-texture development copper tubes drawn with a tilted die was investigated using three methods: synchrotron, neutron diffraction, electron backscatter positions maximum minimum wall thickness tubes. Understanding how is main aim study. The results EBSD examinations showed same behavior at sides as-received tube, as observed synchrotron diffraction method well macro-texture measurements. cube component found be predominant orientation tube. However, it almost disappeared after drawing −5° tilting. By contrast, Cu increased significantly. Before drawing, varied strongly across thickness. After however, there no noticeable gradient analyses tilting not creating an inhomogeneous over circumference.
