is its lack of permanent magnetism. Above the Curie point, thermal agitation overcomes the alignment of magnetic moments found in ferromagnetic constituted a separate phase of matter, modern science

In metallurgy, ( ) refers to a specific non-magnetic state of iron that occurs when alpha iron ( ) is heated above its Curie temperature ( constituted a separate phase of matter

: It maintains the Body-Centered Cubic (BCC) lattice structure of . Unlike other transformations (like α→γalpha right arrow gamma

). Historically considered a distinct allotrope, it is now primarily viewed as the high-temperature, paramagnetic form of ferrite. Key Features and Characteristics While it was once debated whether

, it undergoes a true allotropic transformation into Austenite ( ), which has a Face-Centered Cubic (FCC) structure.
