Abstract

The press for processing of metallic materials makes use of the phenomenon known as superplasticity. Relatively low pressures ar eused and no noise is generated. The metallic material is subjected to a temperature cycle which exceeds the transformation point and is also subjected simultaneously to a light mechanical load. In the press the workpiece on the lower tool is moulded by the ram while the workpiece is heated electrically above the transformation temp. and subsequently cooled for a number of these cycles. The pressure force applied in one tenth to one twentieth in comparison with that used for conventional plastic forming.
