What is body centred cubic lattice?

A body-centered cubic (BCC) lattice is a type of arrangement in which atoms are arranged in a cubic structure with an atom at the center of the cube. This structure is commonly found in metals such as iron and chromium. It has a coordination number of 8 and is denser than a simple cubic lattice.


When carbon is added to iron the lattice becomes?

When carbon is added to iron, the lattice structure transforms from pure iron's body-centered cubic to a face-centered cubic structure. This transformation results in the formation of steel, which has improved strength and hardness compared to pure iron.


What is the crystal system of iron?

Iron crystallizes in two primary forms depending on the temperature: at room temperature, it adopts a body-centered cubic (BCC) structure, known as alpha iron (α-Fe). At higher temperatures, it transitions to a face-centered cubic (FCC) structure, referred to as gamma iron (γ-Fe). These crystal structures significantly influence iron's physical and mechanical properties.


What are two examples of a cubic crystal system?

Two examples of cubic crystal systems are the face-centered cubic (FCC) structure, found in metals such as copper and aluminum, and the body-centered cubic (BCC) structure, found in metals such as iron and chromium.


What is the allotropic transformation of pure iron?

Pure iron undergoes an allotropic transformation between two primary forms: alpha iron (ferrite) and gamma iron (austenite). At room temperature, iron exists as alpha iron, which has a body-centered cubic (BCC) crystal structure. When heated to temperatures above 912°C (1,674°F), it transforms into gamma iron, characterized by a face-centered cubic (FCC) structure. This transformation significantly affects the metal's properties, including its strength and ductility.
