摘要： An elevated temperature forming die apparatus comprising a lower die part having a first upper surface positioned to engage a lower surface of a first region of such a workpiece, an upper die part supported for reciprocal motion relative to the lower die part, the upper die part having a lower surface that engages an upper surface of a second region of a sheet material workpiece, heaters in thermal communication with the die parts, and a third die part having an upper surface that engages a lower surface of the second region of a sheet material workpiece whose first portion is positioned between the upper and lower die parts, the third die part being supported for reciprocal motion relative to the upper die part such that closure of the upper die part along the first stroke portion against the third die part will clamp the first portion of the workpiece between the upper and third die parts, and the third die part being supported for reciprocal motion relative to the lower die part such that, once the first portion of a workpiece has been clamped between the upper and third die parts a draw region of the workpiece extending adjacent an interface between the first and second portions of the workpiece can be drawn by displacing the lower die part relative to the clamped-together upper and third die parts along a second portion of the die set stroke.

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.
