结果表明，简单剪切是金属加工中组织和织构形成的一种“接近理想”的变形方法。等通道转角挤压（ECAE）是实现这一方法的一种特殊的工业过程。与传统的金属加工操作相比，该工艺具有许多优点;最重要的是，可以在相对较低的压力和载荷下产生超大，严格均匀和单向的变形，用于大批量产品。在各种金属和合金的结构和物理机械性能中观察到的不寻常的效应表明简单剪切法在材料合成和加工中有许多新的应用。
It is shown that simple shear can be considered a ''near ideal'' deformation method for structure and texture formation in metal-working. Equal channel angular extrusion (ECAE) is a special industrial process employed to realize this method. In comparison with traditional metal-working operations, this process has a number of advantages; the most important is that extra-large, strictly uniform and unidirectional deformations can be produced under relatively low pressure and load for massive products. The unusual effects that are observed in both the structure and physical-mechanical properties of various metals and alloys suggest many new applications of the simple shear method in materials synthesis and processing.
