Microstructure modelling guided design of high-strength and damage-tolerance steels

Junhe Lian, RWTH Aachen, Aachen, Germany

The properties of steels must be continuously improved to perform well in the challenging competition with other materials on the one hand and to fulfil sustainability requirements on the other hand. However, for the optimization of steel mechanical properties, the conventional measures have been widely exploited for many steel grades, so that tailoring the microstructure is becoming one of the most promising measures for future steel developments. This study, therefore, aims to provide a modelling approach for the computer-assisted design of damage-tolerant microstructures. It presents an approach to translate the component performance requirements to desired mechanical property profiles and further to the optimized microstructural configurations. Instead of using the deductive cause-effect designing approach, the project aims to apply the inductive goal-means approach, which allows the design starting from the performance of components to microstructure of materials.
