This paper provides valuable insights into the complex dynamics of peritectic solidification in an Al-Mn alloy. The use of quasi-simultaneous synchrotron X-ray diffraction and tomography allows for in-situ, real-time observation of phase nucleation, growth, and their spatial relationships. The study's findings on the role of solute diffusion, epitaxial growth, and cooling rate in shaping the final microstructure are significant for understanding and controlling alloy properties. The large dataset (30 TB) underscores the comprehensive nature of the investigation.
Key Takeaways
- •Real-time observation of peritectic solidification using advanced techniques.
- •Detailed analysis of solute diffusion and its impact on phase formation.
- •Identification of epitaxial growth mechanisms and orientation relationships.
- •Demonstration of cooling rate's influence on microstructure and defect formation.
- •Establishment of a framework for tailoring peritectic structures.
