Ferrite is also known as

• A. Beta
• B. Gamma
• C. Delta
• D. Alpha

Answer: (D)

Ferrite is alpha iron. At room temperature, iron exists in a body-centered cubic form called alpha-iron (α-Fe), which is the ferrite phase. This phase dissolves only a tiny amount of carbon and is soft, ductile, and magnetic. Gamma iron is austenite (FCC) formed at higher temperatures, delta iron is the high-temperature BCC phase near melting, and beta iron isn’t the name used for ferrite in this context. So ferrite is known as alpha.
