大应变挤压加工是一种用于制备块体纳米结构材料的严重塑性变形方法。这种方法结合了机械加工形成切屑时大应变变形所带来的固有优势，以及在单一变形步骤中同时进行挤出尺寸控制。在大应变挤压加工中，通过适当控制变形的几何参数，可以得到尺寸可控的片状、板状和棒状的块体纳米结构材料。
Large strain extrusion machining (LSEM) is presented as a method of severe plastic deformation for the creation of bulk nanostructured materials. This method combines inherent advantages afforded by large strain deformation in chip formation by machining, with simultaneous dimensional control of extrusion in a single step of deformation. Bulk nanostructured materials in the form of foils, plates, and bars of controlled dimensions are shown to result by appropriately controlling the geometric parameters of the deformation in large strain extrusion machining.
