spinodalkäyrä
A spinodalkäyrä, meaning "spinodal curve" in Finnish, is a concept used in thermodynamics and materials science. It describes a boundary in a phase diagram separating a stable phase from a region where the phase is metastable. Beyond the spinodalkäyrä, a homogeneous phase is unstable and will spontaneously decompose into two or more phases. This decomposition occurs through a process known as spinodal decomposition, which is a nucleation-free mechanism.
The spinodalkäyrä is distinct from the binodal curve, which represents the boundary between a stable single
The location of the spinodalkäyrä depends on factors such as temperature, pressure, and composition. It is often
