Abstract:
A method of making a part is provided. A blank is loaded into a die assembly having a pair of shoes with forming pieces attached thereto and compressible members sandwiched between the shoes and the forming pieces. The die is closed about the blank to deform the blank into a part. The die is then opened by a predetermined distance while at least one of the compressible members deforms elastically to maintain contact between at least one of the forming pieces and the part. Less than the entire surface of the part is then conductively cooled through the at least one forming piece to provide a predetermined portion of the part with a predetermined microstructure.
