asymmetric extracting method, extracted materials fabricated by using the method, dice for asymmetric extraction and asymmetric extraction apparatus

摘要

asymmetric extrusion method , which uses an extruded extrusion , extrusion dies for asymmetric and asymmetric extrusion apparatus is provided . According to the asymmetric extrusion method , extrusion through a die containing a hole having an asymmetrical shape relative to the size of the hole and the multi-stage extrusion direction of the extruded material pushes the blood in the blood extruded material extruded material extruded material P while the multi-stage of the shear strain induced can be extruded . ;
