Abstract
The vehicle industry strives for weight reduction in order to reduce fuel consumption. This leads to the development of new steel grades that are enriched with light metals, such as aluminium. In addition to the reduction in density, this means that the properties of conventional steels need to be at least replaced or ideally even surpassed. In the present work, a novel material, ultra-high-carbon (UHC) lightweight steel, was investigated for its forming behaviour. In addition to extrusion tests for this material, comprehensive material characterisation was carried out. The temperature, strain and strain rate–dependent flow behaviour were determined. Furthermore, ring compression tests were performed to identify the temperature and tool-workpiece-dependent friction factors. The findings served as a basis for a material model to perform numerical simulations in order to develop the tool for the extrusion of piston pins. The extrusion took place at 1050–1150 °C in a screw press. This work provides a basis for the forming of hard and solid steels that are difficult to process and can be applied to metals of similar properties.
