Austenite is a face-centered cubic (FCC) form of iron and is one of the key phases in the iron-carbon alloy system, particularly in steel. It is stable at high temperatures and can exist at room temperature in certain alloy compositions. Austenite is named after the British metallurgist Sir William Chandler Roberts-Austen. To be more specific: 1. **Structure**: Austenite has a face-centered cubic crystal structure, which contributes to its ductility and toughness.
