Solidification processes

Your needs

• Alloys treatment by solidification processes (molding: continuous and semi-continuous casting, welding, brazing, etc.) and by additive manufacture
• Improve the quality of metallurgical products produced by solidification
• Understand the metal alloy solidification (crucial step for many materials)

Our solutions

• Experimental study associated with modelling for the understanding of fundamental physico-chemical phenomena applied to solidification
• Study solidification structures (primary grain size, morphology and texture, intergranular, intermetallic microstructure) and defects (chemical segregation from grain scale to the massif, porosity)
• Topics studied: 
  - Grain refinement 
  - Dynamics of the Mushy area 
  - Molding and assembly processes  
• Solid calculation code implemented for the modelling of structures and segregation during the solidification process
