The objective of subproject B1 of CRC 1153 is to determine the formability of novel hybrid semi-finished products by means of incrementally forming cross-wedge rolling. The main aspect is the forming of differently produced hybrid semi-finished products made of steel, aluminium and hard material alloys. In addition, process variables (e.g. temperature and force) are to be measured in the tool-workpiece contact, and the functional integration of the components is to be increased by means of integrated gearing teeth.
