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
