Beta - Iron

In the late 1800s, metallurgists noticed that when iron reached roughly 768∘C768 raised to the composed with power C

(the Curie point ), its physical properties seemed to shift. They categorized iron into distinct Greek-lettered phases based on temperature: Stable, magnetic iron at room temperature. Beta ( ): What they thought was a new non-magnetic phase. Gamma ( ): A legitimate structural change starting at 912∘C912 raised to the composed with power C The Scientific "Twist" beta iron

💡 The "Beta Iron" story is a classic example of scientific evolution, where better tools revealed that a supposed "new form" of metal was just a familiar one behaving differently. In the late 1800s, metallurgists noticed that when
