METHOD OF HOT-MOLDING AT LEAST ONE METAL SHEET CONSISTING OFMATERIAL DIFFICULT TO BE DEFORMED

摘要

Process for the hot forming of sheets (5) made of a material that is difficult to work, especially of a dispersion-hardened high-temperature alloy by hot-isostatic pressing in one operation against the contour of a mold (1) serving as negative form in a container (2) that is under vacuum (6) and closed by a cover (3) with welding seam (4). In addition, joining of several sheets (5) to form one body (9) of complicated shape by the diffusion bonding process at the end of the hot-isostatic pressing in one heat in the same single operation.
