Special Session 2 FUNDAMENTAL DIFFUSION PROCESSES, REACTIONS AND PHASE STABILITY IN MATERIALS (SS2)

This special session will encompass all aspects of self-diffusion, diffusion in multi-component and high-entropy alloys, thermo-diffusion, reactions and phase decomposition occurring in solids. Both experimental and theoretical (computational) approaches as well as fundamental and applied aspects will be covered.

Topics of the special session include:

• Measurement techniques,
• Theoretical Description,
• Modelling,
• Tracer diffusion,
• Diffusion in multi-component alloys,
• Diffusion in high-entropy alloys,
• Thermo-diffusion,
• Kirkendall effect,
• Diffusion of multilayers,
• Diffusion-controlled precipitation processes,
• Oxidation of alloys,
• Formation and Ordering: Intermetallic phases,
• Diffusion under external forces (electric, magnetic, stress, plastic deformation, etc)
• Grain boundary diffusion, grain boundary segregation and grain boundary phase transitions
