Abstract
In the project "EcoForge: Resource-efficient process chains for high performance parts" a new efficient forging process chain is developed, which allows a saving in energy of more than 30 %. This process chain will be optimized for highstrength ductile bainitic steel (HDB). The forging heat is directly utilized to substitute reheating process steps by a controlled heat treatment. The microstructural transformation is controlled by the use of a flexible spray field. Simultaneously the microstructural state is detected by an eddy current sensor. This detection is in-situ and online. The heat treatment is followed by further process steps, such as machining and forging at elevated temperatures. These process steps are performed in a temperature range of 300-500 °C in order to decrease the mechanical forces impacting on forging and cutting tools. The created microstructures are quantitatively investigated by a newly developed SEM-image analysis routine. Simultaneous to the experimental analyses, detailed numerical investigations are performed to simulate the microstructural evolution and the whole process chain by means of suitable numerical models.
