Sulatusuunia
Sulatusuunia is a term used in materials science and related fields to describe the preferred orientation or direction of melting and melt migration within a solid material when it is subjected to a thermal gradient or compositional gradients. The concept captures the observation that melting often proceeds more rapidly along certain crystallographic directions, grain boundaries, or interfaces rather than uniformly throughout the material.
The phenomenon arises from anisotropies in the solid, such as differences in crystal structure, interfacial energy,
In practical terms, sulatusuunia is relevant to processes where controlled melting and melt flow are important.
Observation and analysis of sulatusuunia typically employ in situ high-temperature imaging, X-ray or electron microscopy, and
