Digital Forgings - Application of ICME and Digital Twins for the Development of Aerospace Forgings

The size and geometric complexity of forgings for the aerospace industry require a great deal of effort in the design of the forging and the development of the optimum production route in order to meet the required property profile of the finished component. The use of ICME (Integrated Computational Materials Engineering) and the development of digital twins for these forgings makes it possible not only to reduce development times and costs, but also to design forging-optimized finished parts, which can then contribute to a reduction in weight and costs.

Using the example of an integral die forging made of the aluminum alloy 7010 and an engine disk made of the superalloy U720Li, process chain simulations were carried out and compared with real results. The advantages of the combined use of ICME and digital twins for property prediction will be presented.
