#phase transition

• Allocure — A structural phenomenon or a process of thermal or chemical treatment through which the crystalline phase or internal structure of a material is modified in a way that differs from its standard thermodynamic evolution. In advanced metallurgy or solid-state physics, the term indicates a controlled deviation in the solidification or crystallization process, generating alternative mechanical properties.
• Allotropic — Pertaining to allotropy or characterized by the existence of multiple molecular or crystalline structural forms of the same chemical element; specific to states where the atoms of a simple substance are arranged in different spatial geometries, generating distinct physical properties despite an identical raw elemental composition. This structural type of molecular behavior controls the phase transitions of many industrial materials.
• Allotropism — A state, property, or structural phenomenon consisting of the capacity of a pure chemical element to exist under several distinct molecular forms or crystalline lattices (allotropy); the set of spatial geometric modifications that the atoms of the same simple substance can adopt, generating substances with totally different physical and mechanical properties, although the raw elemental composition remains identical.
