SFB 1232:  From colored states to evolutionary structural materials

• Subject Area: Mechanical and Industrial Engineering ; Computer Science, Systems and Electrical Engineering ; Materials Science and Engineering ; Thermal Engineering/Process Engineering
• Term: from 2016 to 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 276397488

The development of application-adapted structural materials is the basis for a large number of future applications in areas such as energy or mobility, which require a specific performance profile. The Collaborative Research Centre 1232 investigates the completely new method "coloured states" of materials development, in which specific requirement profiles are realised through a combination of chemical material composition and thermal, mechanical or thermomechanical processing.The basic hypothesis for this method is the mapping of quickly determinable descriptors to standardized material properties using a predictor function. The various descriptors are determined on micro samples in high throughput. This procedure of combined material and process design in high throughput is scientifically completely new for structural materials whose properties result from the interaction of different material components within a microstructure. In the future, it should enable rapid identification of new materials and their processing on the basis of economically and environmentally sound concepts for specific requirement profiles. The number of possible alloying concepts and processing variants for metallic structural materials is almost unlimited, and a very large number of states, which are similar to a broad colour spectrum in their variety and density of variation. The method used to identify specific solutions in this large search space is therefore called "Farbige Zustände" (“colored states”), also as a metaphorical link to the tempering and annealing colors of steels.
