Research Areas

Our research group focuses on Computational Thermodynamics and its applications in materials and metallurgical engineering, a vital component of Integrated Computational Materials Engineering (ICME). We aim to develop accurate Gibbs energy models for solid crystalline metal phases, with particular emphasis on modeling short-range ordering (SRO) effects, using advanced methods like the Cluster Variation Method (CVM). This work is crucial for designing advanced materials such as high-entropy alloys, Ti-based composites for defense, bioimplants, and energy storage systems. Our research combines experimental techniques (e.g., drop calorimetry, DSC) with first-principles calculations (e.g., DFT) to acquire thermochemical data, and we develop CE-CVM-based algorithms to predict phase diagrams and optimize material properties. We also contribute to CALPHAD and CE-CVM database development, supporting the design and processing of novel materials.

More specifically, we are interested in:

  • Titanium-based systems
  • Binary, ternary, and multicomponent transition metal systems
  • Compositionally complex alloys (CCA and HEA)
