Interfacial reaction and diffusion kinetics at the solid-liquid phase boundary of compound partners in the Al-Cu-Zn system: Experiments and multiscale simulations

The combination of materials with different properties in one component leads to hybrid components with improved properties. The composite casting process is an efficient method for manufacturing such components. The development of the intermetallic phases plays an important role in the performance of the final product. Therefore, it is crucial to understand and control the formation and growth of these phases in order to optimize the strength of hybrid components.

The aim of the project is to create a sequential multi-scale model to predict the growth of intermetallic phases between aluminum and brass in composite casting. This offers the possibility to determine suitable process parameters for a strong bond in composite casting and thus to optimize the production of hybrid components.

Project partners: Professor Babette Tonn, Head of the Foundry Technology Department, Professor Harald Schmidt, Head of the Solid State Kinetics Department and Junior Professor Nina Merkert, Chairwoman of the Clausthal-Göttingen Simulation Science Center (SWZ) are involved in the project.
