Beta Iron 〈FAST - 2025〉

: 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. Technical Comparison of Iron Phases Common Name Crystal Structure Magnetic State Temperature Range Alpha ( ) Ferromagnetic Beta ( ) Beta Iron BCC Paramagnetic Gamma ( ) Non-magnetic Delta ( ) Delta Ferrite Non-magnetic (PDF) The Beta Iron Controversy Revisited - ResearchGate

: Most contemporary iron-carbon phase diagrams omit the "beta" label because it is not a crystallographically unique phase; the entire BCC region is typically just labeled as beta iron

constituted a separate phase of matter, modern science defines its unique features through its magnetic and structural behavior: : The defining feature of : Because it shares the BCC structure with

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
