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.
