| Abstract Scope |
The ESA project METCOMP investigates peritectic solidification using a multi-scale approach that combines metallic Cu-Sn alloys, an organic model material (TRIS-NPG), and advanced phase-field simulations.
Peritectic transformations are highly sensitive to thermodynamic and kinetic conditions. METCOMP studies these transformations under both terrestrial gravity and microgravity aboard the International Space Station.
Directional solidification experiments were performed using the Bridgman technique on the metallic Cu-Sn system and the transparent organic model system TRIS-NPG. The organic system enablesr real-time observation of interface morphologies, providing insights not accessible in opaque metallic systems.
This work presents a comparative analysis of solidification morphologies in TRIS-NPG and Cu-Sn under different gravity conditions, highlighting both the advantages and limitations of using TRIS-NPG as a model for studying peritectic solidification.
Significance: Understanding peritectic solidification under microgravity provides valuable insights for controlling microstructures in advanced materials processing, both in space and on Earth. |
