tracerdiffusjon
tracerdiffusjon, also referred to as tracer diffusion, is the process by which individual atoms or ions migrate through a solid lattice, often tracked by a distinct isotope or marker. The concept originated in the early 20th century with the work of scientists such as Charles Kittel and G. S. Shapiro, who used radioactive tracers to quantify atomic mobility within crystalline structures.
In a crystalline solid, atoms occupy fixed lattice sites but constantly vibrate around them. When an atom
The diffusion coefficient follows an Arrhenius relationship: D = D₀ exp(-Q/RT), with D₀ as the pre-exponential factor,
Tracer diffusion plays a critical role in materials engineering. It influences alloy homogenization, corrosion processes, and
Experimental techniques for measuring tracerdiffusjon include secondary ion mass spectrometry, thermal diffusion analysis, and the use
