The present contribution illustrates the role of the triple line in solid-state microstructural evolution. In single-phase materials, the role of the triple line in grain growth phenomena is discussed. In surface alloying, it is shown that the contact angle at the interface plays a key role on the kinetics of the process. In discontinuous precipitation, it is shown that the conditions at the triple line removes the degeneracy of the problem of spacing selection.
