摘要： Age-hardened aluminum alloy sheet can be subjected to a shearing operation, such as trimming or piercing, with reduced sliver formation by first heating the region to be sheared to a temperature above about 250.degree. C., immediately quenching the heated region to soften the region, and then performing the shearing operation in the softened region before age-hardening occurs.

摘要： An elevated temperature forming system in which a sheet metal workpiece is provided in a first stage position of a multi-stage pre-heater, is heated to a first stage temperature lower than a desired pre-heat temperature, is moved to a final stage position where it is heated to a desired final stage temperature, is transferred to a forming press, and is formed by the forming press. The preheater includes upper and lower platens that transfer heat into workpieces disposed between the platens. A shim spaces the upper platen from the lower platen by a distance greater than a thickness of the workpieces to be heated by the platens and less than a distance at which the upper platen would require an undesirably high input of energy to effectively heat the workpiece without being pressed into contact with the workpiece.

摘要： The present invention provides a method of embossing or imprinting patterns in the surface of a sheet metal article using superplastic forming at suitable SPF temperatures. A template having a pattern is interposed between a forming tool and a sheet metal blank. Gas pressure is applied to the sheet metal blank. This pressure forces the sheet metal against the surface of the lower forming tool having the template there between. The sheet metal blank is stretch formed according to the contours of the surface of the lower forming press and the template. The embossed and shaped sheet metal part is then removed from the forming tool.

摘要： A method is disclosed for temporarily bonding reinforcing sheet metal pieces or other metal pieces to a sheet metal blank for forming at an elevated temperature such as is employed in superplastic forming of suitable aluminum, magnesium, stainless steel or titanium alloys. The pieces are bonded to the blank in locations in which the piece will acquire a desired shape from co-formation with the blank. Suitable water suspendible sodium silicate compositions, such as water glass bond the piece to the blank during high temperature forming and permit removal after forming.

摘要： Pre-straining and thermal recrystallization processes for maximizing formability in SPF sheet alloys of aluminum, magnesium, iron and titanium can be modified to form sheet products with roughened or textured surfaces for low-slip applications or coating adherence or decorative applications. By determination of suitable pre-strain levels and recrystallization/forming temperatures for s sheet metal stock, relatively large grained microstructures are formed in the sheet that yield useful surface texture during forming.

摘要： A method is disclosed for stretching sheet blanks, especially superplastic sheets, by differential gas pressure into conformity with a female die surface without encountering excessive thinning or tearing of the sheet. The warmed SPF sheet is draped over a preformed surface to draw more of the sheet material into the die cavity before the edges of the sheet are fixedly clamped whereby the additional formable material is used in forming the product, thereby reducing thinning and tears.
