The DFG Priority Program Compositionally Complex Alloys - High Entropy Alloys (CCA - HEA), see www.sppccahea.de, is presented. The second and last phase ends in 2023. Unfortunately, many activities could not fullfilled in the last two years, so now the hope is taht this work can be established in 2022/2023. Current results of the Chair of Metallic Materials at the University of Bayreuth within the SPP will be presented. Firstly, with regard to CCA (two-phase) with an application target in the medium to high temperature range. Secondly, various HEA (single-phase), whereby the focus here is currently more in the area of basic research. In Bayreuth, fcc, bcc and hcp single-phase HEA are investigated.
