研究了两种不同模具角度下铜的等通道转角挤压变形织构。对于不同的模具角变形的试样，被发现的优选取向不同，这是由于不同的模具角的剪切平面相对于测量平面的不同取向。研究表明，不同模具角度产生的ECAE变形织构可以根据ECAE中剪切面的晶体学取向和剪切方向进行分析。发现ECAE中的剪切方向基本上平行于铜中的110 μ m方向。这项研究证实了ECAE技术确实产生了类似于简单剪切（扭转）的变形织构。
The deformation texture of copper processed by equal channel angular extrusion (ECAE) was investigated with two different die angles. For specimens deformed by different die angles, the preferred orientations were found different, which was attributed to the different orientations of the shear plane with respect to the measuring plane for different die angles. It has been demonstrated that the ECAE deformation texture resulted from different die angles can be analyzed in terms of the crystallographic orientations of the shear plane and the shear direction in ECAE. The shear direction in ECAE was found essentially parallel to the 〈110〉 direction in copper. This study has confirmed that the ECAE technique does produce a deformation texture similar to that of simple shear (torsion).
