摘要： The present invention suppresses deterioration in the corrosion resistance of a worked portion resulting from working cracks in a Zn-based plated layer (3) in a workpiece (2) formed into a predetermined shape by performing plastic working on a Zn-based plated steel sheet (1) coated with a Zn-containing metal as a raw material. That is, plastic working is performed on a raw material that is a Zn-based plated steel sheet (1) to obtain a workpiece (2) having a predetermined shape, and thereafter, pressurization processing is performed on a worked portion in a sheet thickness direction to deform the plated metal, thus decreasing the width of working cracks in the plated metal. Accordingly, it is possible to reduce the deterioration in the corrosion resistance of the worked portion of the Zn-based plated workpiece.

摘要： A lithium-ion secondary-battery case that allows bonding without weld spatter and has high strength against external force acting on the battery case, and a method for manufacturing the lithium-ion secondary-battery case are provided. Specifically, an austenitic stainless steel foil is used for a cup component (2), and a two-phase stainless steel having an austenite transformation start temperature AC1 in a temperature increase process at 650° C. to 950° C. and an austenite and ferrite two-phase temperature range of 880° C. and higher, is used for a cover component (3), and the diffusion bonding is proceeded while accompanied by grain boundary movement upon transformation of the two-phase steel from a ferrite phase into an austenite phase within a heating temperature range of 880° C. to 1080° C.

摘要： A formed material is manufactured by performing forming including at least one drawing-out process and at least one drawing process performed after the drawing-out process. A punch 31 used in the drawing-out process is formed to be wider on a rear end side than on a tip end side. By pushing a raw material metal plate into a pushing hole 30a together with the punch 31, ironing is performed on a region of the raw material metal plate corresponding to a flange portion.

摘要： An ironing mold according to the present invention includes a punch that is inserted into a formed portion, and a die having a pushing hole into which the formed portion is pushed together with the punch. An inner peripheral surface extends non-parallel to an outer peripheral surface of the punch, and the inner peripheral surface is provided with a clearance that corresponds to an uneven plate thickness distribution, in the pushing direction, of the formed portion prior to the ironing relative to the outer peripheral surface to ensure that an amount of ironing applied to the formed portion remains constant in the pushing direction.
摘要翻译： 根据本发明的熨烫模具包括插入到成形部分中的冲头和具有推动孔的模具，所述成形部分与冲头一起被推入其中。 内周表面不平行于冲头的外周表面延伸，并且内周表面设置有相应于在熨烫之前的成形部分的推压方向上的不平坦板厚度分布的间隙 以确保施加到成形部分的熨烫量在推动方向上保持恒定。

摘要： A formed material manufacturing method according to present invention includes the steps of forming a convex formed portion by performing at least one forming process on a surface treated metal plate, and performing ironing on the formed portion using an ironing mold after forming the formed portion. The ironing mold includes a punch that is inserted into the formed portion, and a die having a pushing hole into which the formed portion is pushed together with the punch. An inner peripheral surface of the pushing hole extends non-parallel to an outer peripheral surface of the punch, and the inner peripheral surface is provided with a clearance that corresponds to an uneven plate thickness distribution, in the pushing direction, of the formed portion prior to the ironing relative to the outer peripheral surface to ensure that an amount of ironing applied to the formed portion remains constant in the pushing direction.
