I'm trying to understand how alloys are classified. I know alloys are mixtures of metals, but I'm curious about the criteria or properties that determine their classification.

Alloys are primarily categorized into two types: substitutional and interstitial, based on the specific atomic arrangement that constitutes the alloy.

Substitutional alloys occur when atoms of one element replace atoms of another element in the lattice structure. This leads to a homogeneous mixture where the alloy retains the same crystal structure as the base metal but with modified properties.

Interstitial alloys, on the other hand, involve atoms of one element fitting into the spaces between the atoms of another element. This arrangement often results in a harder and stronger alloy compared to its constituent metals.

Beyond their classification as substitutional or interstitial, alloys can also be categorized as homogeneous or heterogeneous. Homogeneous alloys consist of a single phase, meaning they have a uniform composition and structure throughout.

Heterogeneous alloys, in contrast, are composed of two or more phases. These phases can differ in composition, structure, or both, leading to alloys with a variety of properties that can be tailored for specific applications.
