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

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

The goal of this project is to create a sequential multi-scale model to predict the growth of intermetallic phases between aluminum and brass during 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: Involved in the project are Professor Babette Tonn, Head of the Department of Foundry Technology, Professor Harald Schmidt, Head of the Department of Solid State Kinetics, and Junior Professor Nina Merkert, Chair of the Board of the Simulation Science Center Clausthal-Göttingen (SWZ).
