摘要： A thin, forged magnesium alloy casing is integrally constituted by a thin plate with projections on either or both surfaces, and the thin plate is as thin as about 1.5 mm or less. The thin forged casing can be produced by (a) roughly forging a magnesium alloy plate to form an intermediate forged product under the conditions of a preheating temperature of the magnesium alloy plate of 350 to 500 °C, a die temperature of 350 to 450 °C, a compression pressure of 3 to 30 kbar, a compressing speed of 10 to 500 mm/s and a compression ratio of 75 % or less; and (b) precisely forging the intermediate forged product under the conditions of a preheating temperature of the intermediate forged product of 300 to 500 °C, a die temperature of 300 to 400 °C, a compression pressure of 1 to 20 kbar, a compressing speed of 1 to 200 mm/s, and a compression ratio of 30% or less.

摘要： The present invention relates to a torsional extreme-plastic processing method capable of replacing a metal spinning process that is a method for processing a conic metal pipe which is mainly used for a projectile such as a bullet, missile, and a nose cone of an airplane. In other words, a processing method in which severe plastic deformation based on torsion and compressive force is applied to a material by using a mold to produce miniaturize and nano-size crystal particles in a conic pipe. According to the severe plastic deformation method of the present invention, a punch that matches an inner shape of the conic metal pipe is mounted inside the conic metal pipe, and then a mold that matches an outer shape of the conic metal pipe is mounted outside the conic metal pipe. Thus, microstructures of the conic metal pipe may be ultra-finely crystallized or nano-crystallized through shearing by applying compression and torsion to the conic metal pipe.
摘要翻译：本发明涉及一种能够代替金属纺丝工艺的扭转极端塑料加工方法，该金属纺丝方法是主要用于飞机的子弹，例如飞机，导弹和飞机的锥体的锥形金属管的加工方法。换句话说，一种加工方法，其中通过使用模具将基于扭转和压缩力的严重塑性变形施加到材料上以在锥形管中产生小型化和纳米尺寸的晶体颗粒。根据本发明的严格的塑性变形方法，将与锥形金属管的内部形状相匹配的冲头安装在锥形金属管的内部，然后将与锥形金属管的外形匹配的模具安装在锥形金属管。因此，通过对锥形金属管施加压缩和扭转，锥形金属管的微观结构可以通过剪切而被超细结晶或纳米结晶。

摘要： A molding method by forging, wherein, a material (1) manufactured by punching out a plate-like member is molded, in an upsetting step, in a first intermediate molded product (2) by molding its peripheral edge part in an annular thin-walled part (21), molding the inside of the annular thin-walled part (21) in a thick-walled part (22) thicker in wall thickness than the annular thin-walled part (21), and forming a recessed part (22A) at the center part of the thick-walled part (22). A gear or a cup-like case with an inner boss is manufactured by using the first intermediate molded product (2). When the cup-like case with the inner boss is manufactured, the first intermediate molded product (2) is molded into a second intermediate molded product (3), in a drawing with ironing step, by molding its thick-walled part (22) in a bottom part (32) and pressing/molding the annular thin-walled part (21) in a peripheral wall part (31) integrally extended from the bottom part (32). The second intermediate molded product (3) is extruded forward and backward to extrude an inner boss (43) on the inside of the bottom part (42) and an outer boss (44) on the outside of the bottom part (42), and an outward flange part (41A) is formed at the outer end edge part of a peripheral wall part (41).

摘要： The invention relates to a computer-implemented process for making a pot that involves: (a) cutting an ingot comprising a refractory metal component into a first work piece; (b) subjecting the first work piece to upset forging, and thereby forming a second work piece; (c) subjecting the second work piece to a first annealing step in a vacuum or an inert gas to a first temperature that is sufficiently high to cause at least partial recrystallization of the second work piece, and thereby forming an annealed second work piece; (d) forging-back the annealed second work piece by reducing the diameter of the second work piece, and thereby forming a third work piece; (e)subjecting the third work piece to upset forging, and thereby forming a fourth work piece; (f)forging back the fourth work piece by reducing the diameter of the fourth work piece, and thereby forming a fifth work piece; (g) subjecting the fifth work piece to a. second annealing step to a temperature that is sufficiently high to at least partially recrystallize the fifth work piece; (h) subjecting the fifth work piece to upset forging, and thereby forming a sixth work piece; (i)subjecting the sixth work piece to a third annealing step, and thereby forming an annealed sixth work piece; (j) rolling the annealed sixth work piece into a plate by subjecting the annealed sixth work piece to a plurality of rolling passes; wherein the annealed sixth work piece undergoes a reduction in thickness after at least one pass and the annealed sixth work piece is turned between at least one pass, and thereby forming a plate; and (k)deep drawing the plate into a pot, thereby forming the pot; in which a fourth annealing step is carried out either (1) after step (j) before step (k), or (2) after step (k). Dimensions of at least one work piece or plate suitable for processing into a pot are pre-determined with a computer-implemented finite element modeling assessment method so that at least one work piece in steps (b)-(j) or plate in step (k) has dimensions that are substantially similar to the dimensions determined by the computerimplemented finite element modeling assessment method.
