DELTA IRON Meaning and
Definition
-
Delta iron is a term used in metallurgy and materials science to describe a specific phase of iron that occurs at high temperatures. It is also known as δ-iron or ferrite delta.
Delta iron is characterized by a face-centered cubic crystal structure (FCC) and is the stable form of iron at temperatures between 1,390 degrees Celsius and 1,530 degrees Celsius. It exists in between the two other common forms of iron: alpha iron (α-iron) at lower temperatures and gamma iron (γ-iron) at higher temperatures.
In terms of its physical properties, delta iron is relatively soft, ductile, and has a relatively low melting point compared to other forms of iron. It possesses a relatively high solubility for carbon, allowing it to readily dissolve carbon atoms within its crystal lattice.
Delta iron is often encountered in the heat treatment of steel, where it undergoes a phase transformation during the austenitization process. As the temperature increases above the eutectoid temperature, delta iron transforms into gamma iron, which has a body-centered cubic (BCC) crystal structure. This phase transformation is critical for altering the mechanical and chemical properties of steel, such as improving its strength and hardness.
Overall, delta iron plays a significant role in the understanding and manipulation of iron and steel alloys for industrial applications, as it represents a distinct phase of the iron-carbon phase diagram and its properties contribute to the behavior and performance of various ferrous materials.

Etymology of DELTA IRON
The term "delta iron" is not commonly used in the English language. However, if you are referring to the term "delta ferrite", it can be traced back to its etymology in metallurgy.
The word "ferrite" comes from the Latin word "ferrum", which means "iron". "Ferrite" refers to a solid solution of iron that has a body-centered cubic crystal structure. This term has been used in metallurgy since the early 20th century.
As for the prefix "delta", it signifies a particular phase or state of a material. In metallurgy, "delta" is often utilized to denote a high-temperature form of a substance. Therefore, "delta ferrite" describes the specific phase of iron that exists at high temperatures, particularly in relation to its crystal structure and composition.
