    • PROBLEM TO BE SOLVED: To provide a method for manufacturing a cold-forged article of an aluminum alloy having high dimensional precision at a low cost while applying a comparatively low forging load.
      SOLUTION: This manufacturing method comprises the steps of: heating an aluminum alloy material at 480 to 580°C; holding the material at the temperature for 0.5 to 5 hours to solution-treat it (S3-1), then quenching (S3-2) it by dipping it in a quenching liquid containing an aqueous forging lubricant kept at room temperature to 70°C to subject the material simultaneously to solution treatment and lubrication treatment. The manufacturing method also comprises cold-forging the quenched material as soon as possible (preferably in less than 2 hours and more preferably in less than 10 minutes) to decrease a forging load by inhibiting age hardening. The manufacturing method can impart sufficient mechanical properties to an article right after having been forged, accordingly can shorten a treatment period necessary for aging the forged article or can omit the treatment, and can make a forging line continuous.

    • 要解决的问题:提供一种在施加较低的锻造载荷的同时以低成本制造具有高尺寸精度的铝合金的冷锻制品的方法。 解决方案:该制造方法包括以下步骤:在480-580℃加热铝合金材料; 将材料在该温度下保持0.5至5小时以进行溶液处理(S3-1),然后将其浸渍在含有保持在室温至70℃的含水锻造润滑剂的淬火液中,骤冷(S3-2) 同时对材料进行固溶处理和润滑处理。 该制造方法还包括尽快(优选在小于2小时,更优选少于10分钟)中对淬火材料进行冷锻以通过抑制时效硬化来减少锻造负荷。 制造方法可以在锻造后立即赋予制品足够的机械性能,因此可以缩短锻造制品的老化所需的处理时间,或者可以省略处理,并且可以使锻造线连续。 版权所有(C)2008,JPO&INPIT

    • PROBLEM TO BE SOLVED: To prevent a metal outer pipe and an FRP inner pipe of a metal/resin composite pipe from being released apart in a cooling process after thermal molding and also, the buckling of the inner pipe/breakage of a material from occurring, in the metal/resin composite pipe.
      SOLUTION: When the metal outer pipe and the FRP inner pipe are molded by heat and under pressure, a fiber-reinforced resin whose ratio of compression strength to compression modulus in the pipe axial direction can meet a specified relationship, is sandwiched between both outer/inner pipes as a buffer layer. Consequently, the compression load of the outer pipe by heat shrinkage in the pipe axial direction, is absorbed by the compression and shear deformation of the buffer layer. Besides, in the pipe axial direction of the composite pipe, the value (Rc2) of the compression strength/compression modulus of a second fiber-reinforced resin is higher than the value (Rc1) of the compression strength/compression modulus of a first fiber-reinforced resin.

    • 要解决的问题:为了防止金属/树脂复合管的金属外管和FRP内管在热成型后的冷却过程中被分离,并且内管的弯曲/断裂 在金属/树脂复合管中发生材料。 解决方案:当金属外管和FRP内管通过热和压力成型时,其压缩强度与管轴向压缩模量之比可以达到规定关系的纤维增强树脂被夹在 外管/内管均为缓冲层。 因此,通过管轴向的热收缩使外管的压缩载荷被缓冲层的压缩和剪切变形吸收。 此外,在复合管的管轴方向上,第二纤维强化树脂的压缩强度/压缩弹性模量的值(Rc2)高于第一纤维的压缩强度/压缩模量的值(Rc1) 增强树脂。 版权所有(C)2007,JPO&INPIT
