摘要： The present invention relates to a composite plate having an improved ductility during cold-rolling, a method of cold-rolling and a method of manufacturing a rolled plate using the composite plate, and a rolled plate manufactured by the methods. Specifically, the present invention relates to the composite plate having an improved ductility during a cold-rolling process including a plate made of a first material and a constraining member made of a second material and suppressing plastic deformation of the plate in the transverse direction, the method of cold-rolling and the method of manufacturing a rolled plate using the composite plate, and the rolled plate manufactured by the methods. According to the present invention, when cold-rolling is performed using the composite plate having an improved ductility during the cold-rolling process including the plate and the constraining member, the constraining member applies compressive stress in the transverse direction of the plate while the rolling process is performed to prevent generation of an edge crack, and a tensile twinning is formed to remarkably improve the ductility of the plate. Therefore, materials such as magnesium or magnesium alloy having low formability in low temperatures and had problems such as high costs due to hot processing and process complication can be used in manufacturing a high-quality plate which can be usefully used in various technical fields such as automobiles, aircrafts, and so forth, by the cold-rolling of the present invention.
摘要翻译：本发明涉及一种具有改善的冷轧延展性的复合板，一种冷轧方法以及使用该复合板的轧制板的制造方法以及通过该方法制造的轧制板。具体而言，本发明涉及在冷轧过程中具有改善的延展性的复合板，其包括由第一材料制成的板和由第二材料制成并限制板在横向上的塑性变形的板，冷轧方法以及使用该复合板的轧制板的制造方法以及通过该方法制造的轧制板。根据本发明，当在包括板和约束构件的冷轧过程中使用具有改善的延展性的复合板进行冷轧时，约束构件在轧制的横向方向上施加压缩应力进行处理以防止边缘裂纹的产生，并且形成拉伸孪晶以显着提高板的延展性。因此，在低温下具有低成形性的材料如镁或镁合金，并且由于热加工和工艺复杂性而导致诸如成本高的问题，可用于制造高质量的板材，其可用于各种技术领域，例如汽车，飞机等，通过本发明的冷轧。

摘要： PURPOSE: A low friction type mold for ECAP(Equal Channel Angular Processing) and a method for improving material using the same are provided to significantly reduce the fractional force between an improvement metal and a plunger by moving the plunger while closing at least three surfaces among the outer surfaces of improving workpiece metal, thereby innovatively blocking the generation of burr. CONSTITUTION: A low friction type mold for ECAP includes a plunger(120), a guide(140), a die(160), and a block(180). The plunger receives and applies an improving workpiece(W) toward a cross direction against the molding direction. The guide is inserted into the inside of the plunger and guides the one surface of the improving workpiece in the transferring direction. The die receives the guide and plunger to reciprocate and changes the transferring direction of material by connecting the movement of the plunger. The block is coupled to the die and forms the part of the transferring channel of the improving workpiece.
