TP7: Thermodynamics and phase diagrams of refractory composites (2020-2022)

The work package TP7 of the researcher group (DFG FOR 3010) studies the thermodynamics and determines phase diagrams of refractory composite materials by a combination of CALPHAD modelling and selected key experiments. The focus is on the development of advanced high temperature materials from the ternary systems Al-Nb-O and Al-Ta-O, respectively. 

DFG project: New sulfur bearing Bulk Metallic Glasses: Thermophysical and mechanical properties (2020-2022)

Partner: University Saarbrücken

Thermodynamic analysis and modeling of novel ternary Ni-S-based bulk metallic-forming systems: The novel Ni-S-based bulk metallic glass (BMG) system Ni-X-S, with X=Pd, Ti, Nb recently discovered by the group of R. Busch are of particular interest. The relative simplicity of the ternary systems in comparison to the commonly found quinary BMG-formers facilitates the application of the CALPHAD modeling (CALculation of PHAse Diagram).

Partners: TU Darmstadt, Dechema Forschungsinstitut

For an efficient development of high temperature materials in the ternary system Mo-Si-Ti as well as the quaternary system Mo-Si-Ti-B it is essential to elucidate the underlying thermodynamics by experiments as well as modelling using the CALPHAD method (CALculation of PHAse Diagrams). It allows the simulation of phase diagrams from the Gibbs free energies of all its phases and constituents.

DFG Project: Lithiated metallic anodes (LixSn1-x) with internal Ga-rich liquid matrix for rechargable lithium ion batteries (2016-2020)

The design the heterogeneous Sn based anode material with a low melting Ga-rich phase as an internal matrix is the objective of this project. Apart from usually time-consuming and expensive evaluations of prototype electrode materials, strategies will be employed to directly correlate thermochemical properties, equilibrium diagrams and electrochemistry by using the CALPHAD method which is up to now the most advanced method for thermodynamic modeling and optimization of complex heterogeneous systems.
