Order-disorder Transition

An order-disorder transition occurs when a material changes from a structured, organized state to a more random, disorganized one, or vice versa. For example, in certain alloys or crystals, atoms are arranged in a precise pattern at low temperatures (ordered). When heated beyond a specific point, this uniform arrangement breaks down, and atoms become randomly distributed (disordered). This transition affects material properties like strength, electrical conductivity, and transparency. It’s a fundamental process in materials science that explains how materials change their internal structure in response to temperature or other conditions.
