Beta Iron -

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

: Because it shares the BCC structure with alpha iron, it possesses similar mechanical properties, though it is slightly less dense due to thermal expansion at higher temperatures.

: It maintains the Body-Centered Cubic (BCC) lattice structure of . Unlike other transformations (like α→γalpha right arrow gamma , it undergoes a true allotropic transformation into

In metallurgy, ( ) refers to a specific non-magnetic state of iron that occurs when alpha iron ( ) is heated above its Curie temperature ( it possesses similar mechanical properties

is its lack of permanent magnetism. Above the Curie point, thermal agitation overcomes the alignment of magnetic moments found in ferromagnetic
