Priority program 1640
“joining by plastic deformation”
State-of-the-art production technology increasingly demands for process reliable joints of dissimilar materials. The driving force behind is on the one hand lightweight construction with regard to an efficient use of resources and on the other hand the request for high-performing products by a selective use of the material’s properties.
New joining techniques based on plastic deformation are able to fulfil these requirements but are usually hardly investigated and the underlying joining mechanisms are still insufficiently understood. However, this fundamental knowledge is a crucial point for the industrial implementation.
In order to close this gap, the priority program 1640 “forming by plastic deformation” was initiated in 2011. Within this priority program, scientists of all kinds of research institutions cooperate to investigate and to advance novel joining processes.
The first of overall three founding periods with a duration of two years each started in October 2012 and ended in late 2014. The current, second funding period will last until the end of this year and focusses on the reproducibility of the joining processes.
Further topics of the second phase are:
- joining mechanisms in metallurgical bonds
- characterization and testing
The proposals for the third and last funding period of the priority program have been granted in August 2016. The third period commences subsequent to the second phase and will last until 2019. The overall issue of the third founding period will be the transfer of the fundamental research works to the industrial application. This does not only include the predictability, but also quality control and process robustness. Further emphasis is put on currently feasible and prospectively possible material combinations.
