The use of newer measurement strategies offers the possibility of efficiently mapping and further developing thermally supported forming processes. By using laser ultrasound measurement, the non-contact and time-bound detection of microstructural changes can be achieved. As a result, there is an opportunity to map the process steps of a thermomechanically coupled forming process of high-strength aluminum alloys in-situ. The focus of this article is on the identification and validation of relevant process parameters using the new measurement method.
