摘要：
A pressurizing forming process includes the steps of applying a higher fatty acid-based lubricant on a surface of a metallic workpiece and/or a forming surface of a forming tool, and forming, wherein a lubricating film including metallic soap is formed on a pressurized-and-contacted interface, at which the surface of the metallic workpiece and the surface of the forming tool are pressed against and are brought into contact with each other, in forming the metallic workpiece by pressurizing with the forming tool. The metallic workpiece and/or the forming tool can be heated prior to or in the forming step.
